compiz crashed with SIGSEGV in regexec()

[soco]

Haven't been doing anything unusual. Unity crashes are common on this machine, though. Since oneiric, it's difficult to get it to start correctly. I suspect there are issues with the driver that are specific to the nv 7700.

[Alex Launi (alexlauni)]

Are you full up to date? This almost seems like a bad library issue.

[soco (soco-n)]

The only error I can recall from updating was within the last week, and I've been trying to update at least once a week if not every few days since the upgarde to 11.10.

I don't recall seeing this recently, so it's probably gone.

[dino99 (9d9)]

That version has reached EOL since a while, so it will not receive update. If that issue still exist, report again using ubuntu-bug.
