Title:

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  New

Bug description:
  Although not selected by user, mythbackend-setup repeatedly reported
  crash and generated this bug report. Seems to be one of several bug
  reports on mythpreviewgen (#811400, #1090326). First occurred last
  night with mythfrontend shut down. Updates were waiting this morning;
  I updated and mythbackend-setup reported crash again thus this report.
