So the bug is in src/gtkmeter.c, where gtk_meter_get_type returns an unsigned int instead of a pointer. This code looked _very_ familiar because the exact same code has already been fixed in jamin! See #848672 Compare jamin from jessie with jackeq from stretch: https://sources.debian.net/src/jamin/0.97.14~cvs~81203-4/src/gtkmeter.c/ https://sources.debian.net/src/jackeq/0.5.9-2/src/gtkmeter.c/ Code search: https://codesearch.debian.net/search?q=gtk_meter_get_type So probably kluppe and timemachine are affected as well. *sighs at code duplication* James
