Comment:
Sorry, but I'm not expert in gdb.

I started users-admin and then, in a xterm, I did

sudo gdb -p 18641

The output was:

At this time, the users-admin window had frozen, almost blank.

I did anyway the...

--------------------------------------

I couldn't do anything inside the users-admin, because it had frozen,
nothing inside the window. Maybe I didn't use well the gdb program. If
you are more explicit, I'll follow any steps you tell me and reproduce
again the bug.
