This bug also affects me. It is probably this bug in Document Foundation's bugzilla: https://bugs.documentfoundation.org/show_bug.cgi?id=131610
It is also probably related to bug #1911072 For me the bug is not stably reproducible. It sometimes occurs on the first time I apply a transition, sometimes only after applying several different transitions. A backtrace log is attached. ** Bug watch added: Document Foundation Bugzilla #131610 https://bugs.documentfoundation.org/show_bug.cgi?id=131610 ** Attachment added: "gdbtrace_crash.log" https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1877559/+attachment/5479360/+files/gdbtrace_crash.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1877559 Title: LibreOffice Impress crash on apply a transition effect to a slide To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1877559/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
