[apport] gnome-panel crashed with SIGSEGV

Binary package hint: gnome-panel

These crashes appear to be happening randomly, at a rate of one every two days. Nothing too serious... I'm on Feisty with compiz 1:0.3.6-1ubuntu3 (if that makes any difference) and with 'nvidia' drivers:

pandis@pandis-laptop:~$ lspci
<snip>
01:00.0 VGA compatible controller: nVidia Corporation GeForce Go 7400 (rev a1)
<snip>

And .xsession-errors has this (not sure if it's relevant though):

(gnome-panel:5940): Gtk-WARNING **: gtk_widget_size_allocate(): attempt to allocate widget with width -9 and height 24
