Bug#1020682: GIMP - segfaults using Text tool on large XCF/JPG image; gimp unstable thereafter; corrupting the gimp config?

[Michael Murphy]

Package: gimp

Version: 2.10.32-1+b1


GIMP segfaults using Text tool on a large image (5421px * 7016px). Image 
format seems to be irrelevant. Segfaults with both RGB 8-bit XCF and JPG.

Crash occurs when resizing the Text window, or just when typing text 
into the Text window.

Repeatable on two separate machines, one machine had a completely fresh 
Debian install including GIMP

After the segfault crash, GIMP is left unstable and now crashes when 
Text tool is used on any image, large or small.

At a guess, something in the GIMP configuration file(s) has been 
corrupted by the segfault.
