Ubuntu 24.04 up to date
Gthumb 3.12.10
All of gThumb's functions work properly except for printing.
It was printing a while back. I don't know how long ago, but it was not long, a few weeks maybe. I updated the system as usual, 1 or 2 times. Now Gthumb crashes when I try to print a jpg. It never has before.
I uninstalled it, reinstalled it and did the same with the printer, a Brother MFC-2710DW. The printer works as expected from other apps, including GNome Image Viewer 45.3.
Gthumb crashes when you try printing.
Note: Don't type the $. It just signifies a command prompt.
Do
$ type -a gthumb
bash: type: gthumb: not found
I found /snap/bin/gthumb-unofficial.gthumb

Try printing. It should work. This fixed the problem for me.
