Title:
  compiz crashed with SIGSEGV in regexec()

Status in compiz package in Ubuntu:
  Invalid

Bug description:
  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.
