 - This *is* a persistent bug.
 - errors.ubutnu.com does not exist
 - this error is not ubuntu-specific. What happens in this case?

Reproduction instructions are quite clearly described on this ticket.

Bug description:
  Binary package hint: compiz

  Compiz crashes when ubuntu starts and then I press Alt+tab. As I can
  see, the source of the problem is Regex matching module. When I
  disable it (and the Animations module, which depends on Regex), the
  problem seems to disappear.
