Guake Crashes on open after changing preferences

[tblommel]

I installed Guake using apt-get and was able to use it just fine, however after changing preferences and closing the application, I now get the following output when trying to launch. I just updated to Ubuntu 22.04.3 LTS

After playing around for a little longer I seem to have found the issue. I first reset my user preferences by finding the guake directory in dconf-editor and selecting Reset recursively. This allowed me to run guake again. I can reproduce the issue reliably by uploading a non-image file to the Background image section. When I close guake and then try to restart it the issue appears. I was able to break guake while placing an .mp4 and a .pdf file, but a .png file works just fine and does not cause issues.

I guess the solution could be to not have your users be dumb and upload non-image files

Made an issue for this at #2205 to track this.
