Thunderbird on Fedora aarch64 doesn't start anymore

[Andreas Reschke]

Hi there, 
Thunderbird didn't start anymore. Same  problem on both systems: Rock5b and Orion O6, both Fedora 43 up2date
Failure:
andreas@rock5b:~$ thunderbird

 (t=1.03385) [GFX1-]: Failed to start v4l2test process

Segmentation fault         (core dumped) thunderbird

Can't find any package contains "/usr/lib64/thunderbird/v4l2test"

How to fix this ?

[Peter Robinson]

Have you filed a bug, or even provided karma, on the thunderbird
update that broke it?

Ultimately it needs to be reported to the maintainer, they're the ones
that can fix it.

There's some discussion at the end of
https://bugzilla.redhat.com/show_bug.cgi?id=2423824 . Several people
are seeing it.

It may be related to
https://bugzilla.redhat.com/show_bug.cgi?id=2420679 , I guess, which
openQA caught.

Possibly Thunderbird also needs
https://src.fedoraproject.org/rpms/firefox/c/ed74b03b2d1fa2e20a2236b3b760a88...
. which looks like it was the fix for the Firefox aarch64 crash. jhorak
found it for Firefox, and he is also the Thunderbird maintainer, but at
a quick look, it seems like he hasn't applied it to Thunderbird yet?
