Bug#1091977: meld: segfault + freeze

[Christoph Anton Mitterer]

Package: meld
Version: 3.22.2-1
Severity: wishlist
Tags: upstream patch
Control: forwarded -1 https://gitlab.gnome.org/GNOME/meld/-/issues/889

Hey.

There’s an IMO particularly nasty bug in current meld versions, which
causes all meld windows (which actually are just one process) to freeze.

Took me quite a while to find a reproducer for that which I’ve reported
then upstream and turns out the underlying issues has already been
fixed in:
https://gitlab.gnome.org/GNOME/meld/-/commit/23bcd8f41d5bf6c23fabd38b0ad9babcfb2fe247
which I’ve verified and can confirm that it fixes the problem.

Not sure when upstream plans for a new release (the above commit is
already 8 months old), ... the patch applies cleanly to  3.22.2 with no
other patches needed to fix the issue.
Maybe you can cherry-pick that commit.

Thanks,
Chris.
