After updating to 22.04 recently, this command has stopped working:
git difftool --tool=meld -y HEAD~1
Viewing (1/15): 'file.txt'
Launch 'meld' [Y/n]? y
Trace/breakpoint trap (core dumped)
fatal: external diff died, stopping at file.txt
I've already tried both reinstalling meld with --reinstall as well as removing it with --purge and --auto-remove and installing again.  No use.
I've also tried to launch meld from the console, but it's breaking as well:
meld ./file1.txt ./file2.txt
Trace/breakpoint trap (core dumped)
Weirdly enough, it seems to be launching fine from the GUI, but that's not what I need.  I need to use it with git difftool.
Is this because of Wayland? Any way I could debug this?
EDIT:
Additional info: meld installed through apt, version 3.20.4-2.
I've also filed a bug on Launchpad, just in case: https://bugs.launchpad.net/ubuntu/+source/meld/+bug/1994970.
