--- Comment #18 from JohnHardy <johnhardy at johnhardyco.com> ---
I just received the email regarding a similar bug where a specific font was
causing the crash (Bug 112180). Then I slowly scrolled through my font list
using the up/down arrows on the scroll bar. When it got to “Helvetica Narrow”
LO crashed. I tried it again, same result. At the point when it was crashing,
all other font names in the drop-down list disappeared, leaving just "Helvetica
Narrow" visible for a brief period until the crash process completed. Perhaps a
deliberate code feature ("This is the font!").

Then I used the Windows 10 font manager to look for that font. There was a
“Helvetica” folder with lots of variations of Helvetica in it, but there was
also an individual font icon next to the “Helvetica” folder with the name
“Helvetica Narrow S Regular”. I deleted that font with Windows font manager. I
restarted LO. Scrolling through the drop-down font list at any speed no longer
causes a crash. So, my problem seems to be solved by finding a troublesome font
and deleting it, as Telesto mentioned earlier. I did not see any correlation of
a specific font until now. Apparently I never did a slow-scroll through the
“Helvetica Narrow” part of the font list using the scroll-bar arrows until now.

However, there is still some strangeness going on with Helvetica fonts (the
short story being, I need to clean up my Helvetica fonts). I still have 4
entries in the drop-down font list:

Helvetica
Helvetica Narrow
Helvetical-Narrow
Helvetica Narrow S

Opening the “Helvetica” font folder reveals 13 variations of Helvetica,
including some duplicates. Here is each font name as described in the Helvetica
folder, followed by the file name and it's source, assuming the data is
accurate:

Helvetica Bold [helvetica-bold.otf File version 001.003 Lexmark]
Helvetica Bold Italic [helvetica-bolditalic.otf File version 001.003 Lexmark]
Helvetica Bold Narrow Oblique [helvetica-narrow-boldoblique.otf File version
OTF1.0.PS 003.000;Core 1.0.22 Copyright (c) 1985, 1987, 1989, 1990, 1997, 1998
Adobe Systems Incorporated.]
Helvetica Bold Narrow Oblique [Duplicate of above item, same data, only one
font file]
Helvetica Medium [helvetica.otf  File version 001.003 Lexmark]
Helvetica Medium Italic [helvetica-italic.otf File version 001.003 Lexmark]
Helvetica Narrow  [unicode.helvetin.ttf” File version 1.0]
Helvetica Narrow  [Duplicate of above item, same data, only one font file]
Helvetica Narrow Bold [helvetica-narrow-bold_0.otf File version 001.003
Lexmark]
Helvetica Narrow Bold Italic [helvetica-narrow-bolditalic_0.otf File version
001.003 Lexmark]
Helvetica Narrow Medium Italic [helvetica-narrow-italic_0.otf File version
001.003 Lexmark]
Helvetica Narrow Oblique [helvetica-narrow-oblique.otf File version OTF1.0.PS
003.000;Core 1.0.22 Copyright (c) 1985, 1987, 1989, 1990, 1997, 1998 Adobe
Systems Incorporated.]
Helvetica Narrow Oblique [Duplicate of above, same data, only one file]

I had to look in the actual font file to get the “...Adobe Systems...” details
from those 2 fonts. Each font is represented in the Helvetica folder by an icon
with “Abg” displayed on it, with those 3 characters displayed in that font
variation. However, the 2 icons representing the 2 versions of “Helvetica
Narrow”, as well as the overall Helvetica folder, appear to have 2 (not 3)
Chinese characters on them. Sorry, I don’t really know if it is Chinese or some
other font, but it is not English. The “Properties” for those two “Helvetica
Narrow” ttf fonts look sketchy, with the bare minimum of information.

Some fonts appear to be from Adobe, others from Lexmark, and two that are of
unknown origin, if the detail information is correct.

Further oddities:

When I select “Helvetica Narrow” it appears as a light italic font when typed
in a document. The font name as it appears in the font drop-down list looks
like a condensed, bold, non-italic font. Also, the word “name” looks like “nam
e” with much too large a space between the “m” and the “e”. So there are
spacing issues.

“Helvetica Narrow S” appears as a light monospace font when typed in a
document, and in the drop-down list. In fact, it looks absolutely IDENTICAL to
“Courier New”. So something strange is going on there.

Helvetica-Narrow: Same results as “Helvetica Narrow”.

I removed the duplicate font Helvetica Narrow (“unicode.helvetin.ttf”) from the
Helvetica folder. This caused the Helvetica folder to return to 3 English
characters “Abg” displayed on the folder.

I still have “Helvetica”, “Helvetica-Narrow” and “Helvetica Narrow” in the
drop-down font list.

There are other oddities, but it seems likely that I need to remove all of my
Helvetica fonts and install known-good ones.
