Does it happen all the time? Or any steps to reproduce? It happened to me once today when the Image worker was retrieving an anime, so it might have to do with the worker threads in the Qt UI.

Sometimes it does not reproduce, but most of the time it does. I tried closing via ctrl+q, the main menu, and the tray. I also tried browsing my list a bit before closing and doing nothing for a while, but I can't seem to figure out when it does not segfault.

As of 0.8.4.r199.ge132db0-1 it segfaults if you press ctrl-c in the terminal window (assumed that you opened it this way), and then try to close it with the regular window control buttons.

I did indeed open it via the terminal (python -m trackma.ui.qt -d), but I did not use ctrl+c to close (or at least not generally). The segfault happens for me even when trying to close the window normally using the methods I described.

Doesn't happen to me, unless I ctrl-c.

FichteFoll commented 1 year ago

I just had the random idea that this might have been caused by the mpris tracker (seeing how it is using a gio loop on a separate (daemon) thread), but after changing the tracker to lsof I can still reproduce the segfault.
