Hi, all. I'm having a lot of trouble with mate-panel, and I haven't been able to locate a definitive upstream issue. This may have something to do with the fact that the segfault actually occurs in libgtk-3.so.0 . Bug link: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=884648 This has been a major issue for several releases of Debian, so I'm asking for help to resolve it and get a fix locked in before Bookworm.
