            Bug ID: 120180
           Summary: File->Open causes crash by unbounded memory growth
           Product: LibreOffice
           Version: 6.0.6.2 release
          Hardware: All
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: mark.jeronimus at gmail.com

Description:
This started after the last time I updated (via apt). It seems to happen with
any spreadsheet file (ods/xlsx) I tried. It doesn't seem to happen with Writer
(I haven't tried other LO editors)

Video: https://youtu.be/2t92nccITRU
Don't mind the list you see at the beginning of the video, most of it was
before the last update. At the end you see the mouse cursor is starting to
skip. This is not a recording artifact. If I waited any longer with killing the
process then the system will become exponentially less responsive to the point
I can only hit the reset button.

Steps to Reproduce:
When it does happen:
 - Open Calc,
 - File -> open, select any spreadsheet file (double-click or press OK)

When it does *not* happen:
 - Open Calc or Writer,
 - File -> open, select any document file

When it does happen:
 - Open Nautilus,
 - Double-click any spreadsheet file

When it does *not* happen:
 - Open Calc,
 - Make an edit,
 - File -> open, select any spreadsheet file

When it does *not* happen:
 - Open Calc,
 - File -> recent, select same spreadsheet file


Actual Results:
Calc fills up memory until PC halts to a grind, unless the process is killed in
time. The time between the program hangs and the user starts feeling
something's wrong is about 40 seconds. The time between when the user starts
feeling something's wrong and when it's too far gone to do anything about it
about 20 seconds.

Expected Results:
Document opens normally.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes
