First steps finding regression bug(s)

[Rodolfo]

Joren,

maybe that string is caught from here (note that's is inside Writer module)
http://opengrok.libreoffice.org/xref/core/sw/source/ui/app/error.src
Then you should try searching for ERR_AUTOPATH_ERROR or ERRCODE_CLASS_PATH.

Or here, but I don't have any idea what is UUI.
http://opengrok.libreoffice.org/xref/core/uui/source/ids.src#168
( ERRCODE_UUI_IO_NOTEXISTS )

I found these matches seraching like this
http://opengrok.libreoffice.org/search?q=%22does+not+exist.%22&project=core&defs=&refs=&path=&hist=

I've tried to use "does not exist.\"" (inserting the quote), but
opengrok ignore it.

Looking at that screenshot on bug report, I'd say the problem is the
filenames are concatenated into a single string separated by a newline
character - but I don't know anything about Mac. Or the message string
is just ugly ;)

I hope it helps.

Rodolfo
