I believe it will dump core because VideoDialog is the parent of MetadataFactory and MetadataFactory is the parent of MetadataDownload, and when you leave ""Watch Videos"" while its trying to download metadata, VideoDialog, MetadataFactory, and MetadataDownload are deleted, even though MetadataDownload::runGrabber() is waiting for tmdb.py to complete. When that command completes, it leads to a call to MetadataFactory::customEvent() in the main event thread, which tries to post a MetadataFactoryNoResult event to its deleted parent VideoDialog, which causes the core dump. Steps to reproduce: * Truncate videometadata table using your favorite database management tool. * In mythfrontend, go to Media Library -> Watch Videos * Say OK when prompted to scan your video directories. * Press ESC as soon as progress box disappears. Within a few seconds, mythfrontend should vanish. mythfrontend --version Please attach all output as a file in bug reports.
