Chronograph version

v49.1-rc2

Reproduction steps

1. chmod u+x Chronograph.AppImage
2. ./Chronograph.AppImage

Expected behavior

The AppImage should be mounted and Chronograph should launch

Actual behavior

The AppImage appears to mount, but Chronograph fails to launch

Additional information

Log from the terminal:

❯ ./Chronograph.AppImage                   
Traceback (most recent call last):
  File "/tmp/.mount_Chrono88UxuK/usr/bin/chronograph", line 26, in <module>
    from gi.repository import Gio
  File "/tmp/.mount_Chrono88UxuK/usr/lib/python3.13/site-packages/gi/__init__.py", line 40, in <module>
    from . import _gi
ImportError: /tmp/.mount_Chrono88UxuK/usr/lib/python3.13/site-packages/gi/_gi.cpython-313-x86_64-linux-gnu.so: undefined symbol: gi_repository_dup_default

This is on Fedora 42. It doesn't seem to use the host lib, so I don't think the Distro is at fault here.

Please, search for /lib64/libgirepository-2.0.so.0 on your machine and tell me if it exists.

I cannot reproduce this error on my machine, so we need to dive deeper into it

It does:

❯ ll /usr/lib64 | grep libgirepository-2.0.so.0
lrwxrwxrwx.  1 root root        24 Aug 11  2025 libgirepository-2.0.so -> libgirepository-2.0.so.0
lrwxrwxrwx.  1 root root        31 Aug 11  2025 libgirepository-2.0.so.0 -> libgirepository-2.0.so.0.8400.4
-rwxr-xr-x.  1 root root    169224 Aug 11  2025 libgirepository-2.0.so.0.8400.4

Would also be odd if it didn't, since it's part of glib:

❯ dnf provides '*/libgirepository-2.0.so.0'
