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.
