Dear Maintainer,

After upgrading nautilus from 50.2.2-2 to 51.0.1-1, it segfaults at
start.

Downgrading it and its dependencies (libnautilus-extension4 and nautilus-data) to 50.2.2-2 solves the issue.

Regards,

Jean-Marc

Control: severity -1 serious

Thank you for taking the time to report this issue. I noticed that the
version of gtk4 you have installed is 4.22.4 from Testing instead of
4.24 from Unstable. I was able to reproduce your issue with gtk4
4.22.4 but not with 4.24. I reported this upstream at
https://gitlab.gnome.org/GNOME/nautilus/-/merge_requests/2141

I am raising the severity as you requested and am uploading nautilus
with the gtk4 dependency increased to 4.24.

Hi Jeremy,

Le 26/09/26 à 11:03, Jeremy Bícha a écrit :

libgtk-4 on my system was pinned in version 4.22 because of this bug:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1146833

Bug solved in the meantime and libgtk-4 upgraded to 4.24.0+ds-2.

I upgraded nautilus and all is okay now.

I am not an expert but I think it is suffisant to avoid this issue.

I suggest to close the bug.

We believe that the bug you reported is fixed in the latest version of
nautilus, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1148722@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
