Bug#728442: Gnome-Shell and Libc6 Segfaults on running of any unlock dialog or gksu

[Mika]

I have had a similar if not same problem for a long while now. I know
I can get around this by running things from terminal as su to root.
But now that I found this I thought I should join in with info.

So whenever I run synaptic from gnome it takes 15 seconds and crashes
the desktop. Whenever I run a program with admin unlock and press
unlock it crashes.

Here are a few log files. Hope we can find the culprit here and fix this.


dmesg :
