OK, it took a while for it to happen again. I've attached the backtrace.

I guess if you remove the call to dh_strip in debian/rules and build
that it should build gitg with debugging symbols.

You will still need to have glib (et al.) dbg packages installed
though.

Please could you get a backtrace to see where this happens? You will
have to build gitg from source and run the binary and make sure you
have the GLib dbg package installed, then simply run gitg in gdb and
ask for a backtrace when it aborts.

Bug#584952: gitg: memory error / assertion failed

[Eric Cooper]

Package: gitg
Version: 0.0.6-3
Severity: normal

I got this crash:

***MEMORY-ERROR***: gitg[9783]: GSlice: assertion failed: 
sinfo->n_allocated > 0
[1]+  Aborted gitg

I had been using a gitg window with "view all branches", and had
recently typed control-R to refresh the view after a commit.  The same
crash happened in an earlier session, but it doesn't happen every
time.
