Comment 2 for bug 31037

I use breezy, with recent updates (dist-upgrade).
It happens once a week or so, but i can't find a pattern in the intervals. My pc is always turned on, (uptime is more dan 50 days) and i make several times per week a conncetion via vnc with my computer.

I am unfamiliar with gdb. Do i need root (sudo) rights before executing gdb $(vino pid) ?
When i now run gdb and typ "thread apply all bt" nothing is visible on the screen. Is there some output, and where? Or is "thread apply all bt" not something to typ..... Or is there only output if something goes wrong?
