I'm running Debian testing / squeeze, and have just upgraded a number of
packages (including libgstreamer0.10-0 and libc6), then after a reboot
found that Pidgin no longer loads. In an attempt to debug the problem,
I ran it from a terminal under strace and got this output (after
interrupting it when it froze):

This is normally a bug in some application using the D-Bus library.

At one point I also got this message:
/
process 3444: arguments to dbus_connection_send() were incorrect,
assertion "connection != NULL" failed in file dbus-connection.c line 3099.
This is normally a bug in some application using the D-Bus library.
ERROR: Caught a segmentation fault while loading plugin file:
/usr/lib/gstreamer-0.10/libgsttaglib.so
Please either:
- remove it and restart.
- run with --gst-disable-segtrap and debug.
\
Removing the gstreamer0.10-ffmpeg package did not solve the problem, but
after removing gstreamer0.10-plugins-good (which includes
/usr/lib/gstreamer-0.10/libgsttaglib.so and is needed for the sound
support) I can now load Pidgin and it works fine (apart from the missing
sound).
I do not have any third-party packages installed, and all my packages
are the latest version (for testing / squeeze).
Best regards,
