Closing and sometimes opening windows in xpra leads to a segfault in libgobject: xpra: segfault at 8ea ip 00007fda2a10544d sp 00007ffd5d0be288 error 4 in libgobject-2.0.so.0.7600.2[7fda2a0db000+33000] likely on CPU 4 (core 2, socket 0) Problem appears since stabilization of glib-2.76. I suspect a relation to change in memory management as tracked in bug #901805. See also bug at xpra project: https://github.com/Xpra-org/xpra/issues/3822 Reproducible: Sometimes Steps to Reproduce: 1. start xpra-server 2. connect to it 3. open/close windows Actual Results: Often this leads to an segfault, resulting in server-crash.
Thanks, I've commented on the upstream issue at https://github.com/Xpra-org/xpra/issues/3822#issuecomment-1546528426 with a hint on how to reproduce.
I've now disabled x265 after upstream suggested it. Is that enough to fix this? I used to use this daily, but I've stopped now.

No, this does not change it. But as I read totaam's response, he just responded to the uninitialized reads, without meaning to connect this to the issue here. Nonetheless, if upstream does not consider x265 stable, it is a good idea to disable it by default, I think. Thanks for your support, James!

Just for the record: 4.4.5 fixes the crashes for me. Thank you to all the people involved, making the OS-community such a nice place to be. :)
Thus closing.
