Package: libreoffice-impress Version: 1:5.4.1-1~bpo9+1 Severity: normal Dear Maintainer, LibreOffice Impress crashed with the following message very frequently (irregularly but usually less than a minute between consecutive crashes): soffice.bin: thread-watch.c :149 : avahi_threaded_poll_stop: l'assertion « !pthread_equal(pthread_self(), p->thread_id) » a échoué. (sorry for the erreor message in French, it says that the assert failed). My investigations lead to the culprit assert in Avahi code [0], but I do not understand this code. However similar looking bugs in LibreOffice and Sane backends [1][2] made me try to disable Avahi in LibreOffice Impress by turning off remote control: Tools -> Options -> Impress -> General -> [ ] Enable remote control [0]: https://github.com/lathiat/avahi/blob/master/avahi-common/thread-watch.c#L149 [1]: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=755309 [2]: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=861112 This solves the crash problem. It is not clear to me what goes wrong between Avahi and LibreOffice but I could reproduce the bug with both the stable and backports versions (stretch). I do not have a machine running testing or unstable, so I did not test these versions.
