my first post here, so bear with a newbie ;)
I'm using Ubuntu 20.04.3 LTS with XFCE. My system is up-to-date (sudo apt-get update/upgrade)
I have been using Gthumb for years without problems. Since a couple of weeks it crashes when I try to resize a picture (jpg). The latest version of Gthumb in the standard repositories is 3.8.0. I uninstalled and installed again to no avail. Later I managed to upgrade to 3.9 and now even 3.12.0 via this page: https://ossmalta.eu/gthumb-3-12-0-released-how-to-install-via-ppa-in-ubuntu-20-04/
I started gthumb from the terminal to see what kind of info would show up: What I did was:
- start gthumb
- open a picture (jpg) (whatever, fault with every picture I tried)
- click on tools--> resize
- ** bang ** program disappears and throws error as show below
$ gthumb
** (gthumb:22679): WARNING **: 17:44:54.779: _cairo_image_surface_create: could not create the surface: invalid value (typically too big) for the size of the input (surface, pattern, etc.)
** (gthumb:22679): CRITICAL **: 17:44:54.779: _cairo_image_surface_copy_metadata: assertion 'dest != NULL' failed
** (gthumb:22679): CRITICAL **: 17:44:54.779: _cairo_image_surface_get_metadata: assertion 'surface != NULL' failed
Segmentation fault
Here I read about the/a similar error (cairo surface related) also being an security issue on Debian, dated 21th of august: https://www.debian.org/lts/security/2021/dla-2749.en.html
On this gitlab page there is mentioning about a fix (one month ago!) that is also Cairo surface related: https://gitlab.gnome.org/GNOME/gthumb/-/commit/3d985d64492d102027fff41b33be391eb450a6de
All this still does not bring me closer to a solution. I can not find anything when I search for, for example :"gthumb crash resize"
Any help or clues highly appreciated. I you want additional info on my setup/system, please ask. I'm not a developer or an expert, but a reasonable experienced Linux user.
Thanks

Edit: corrected a typo Ubuntu 20.04.2 changed into 20.04.3 Edit 2: I have uninstalled and installed gthumb 3.8. Edit 3: A bug report has been filed now as well
EDIT 4: I managed to take a screenshot just before Gthumb vanishes(crashes) , just after clicking 'resize'
As you can see the 'height' of the picture has absurd size (157933 pix.) and the aspect ratio is accordingly.... I don't know what comes first, the aspect ratio followed by calculated size or vice-versa.
QUESTION: I would like to know where Gthumb stores its preferences to see if there is a preference saved previously that causes this absurd aspect ratio for example
