firejail version 0.9.72

Note that we do not maintain that version of firejail:

Versions other than the latest usually have outdated profiles and may contain
bugs and security vulnerabilities that were fixed in later versions.

How is that a duplicate of the File dialog crashes issue. I think it's maybe a duplicate of #7057

@kmk3 commented on GitHub (Mar 21, 2026):

a duplicate of #7057

Because of the gdk-pixbuf warnings/errors.

But indeed there may be other issues as well.

Removing duplicate status and leaving the issue closed due to the firejail
version being too old and unsupported.

If the problem happens with firejail 0.9.80, please open a new bug report and
follow the bug report template:
