Title:
  update-manager crashed with SIGSEGV in cairo_region_is_empty()

Status in “update-manager” package in Ubuntu:
  Invalid

Bug description:
  update-manager crashed right after an update, when checking again for
  updates. I updated some packages and after these updates were
  installed I checked for updates that were now installable, but update-
  manager crashed, so I couldn't update them. After I restarted update-
  manager it worked.
