Gnome control center crash on launch with "undefined symbol: GST_CAT_DEFAULT"

[Daniel Elbirt]

Gnome Control Center unable to launch. Suspicious of interaction with libwebkit2gtk. Throws the following error on launch:

`gnome-control-center: symbol lookup error: /lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37: undefined symbol: GST_CAT_DEFAULT`

`nm -D` output for the .so file returns `U GST_CAT_DEFAULT`

`ldd` output for the package attached, in case it hints at the root cause.

Thank you for your bug report. Could you share the output of

$ldd -r /lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37

?

[Daniel Elbirt (delbirt)]

Attached ldd output.

[Sebastien Bacher (seb128)]

Thanks, I don't see anything weird in the log and the packages version seem correct ... what's the output of

$ debsums libgstreamer1.0-0

?

Output below:

Solved.

Upgraded to gstreamer 1.24.4, using instructions here:
https://www.linuxfromscratch.org/blfs/view/svn/multimedia/gstreamer10.html

BUT, with the setup flag gst_debug=true

This traces back to an issue with gstreamer debug symbols, patched here:
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/commit/2e1eaaec5e450b9fec035449958ecfef4302f720

it's a bit confusing, so your issue with gstreamer which you locally built to resolve?
