totem 43.0-2ubuntu1
Totem crashes (most of the time) when opening a video file. When it does crash, it crashes before playing the video at all.
It doesn't crash often when being run under gdb, profilers, or other utilities that may slow down execution. That indicated it may be a threading issue or race condition, and after digging deeper the issue is evident from the assert message.
[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
A similar issue happened in SDL, where XInitThreads was *supposed* to be called but wasn't called early enough, specifically by the NVIDIA libGL implementation (525.60.11-0ubuntu0.22.10.1) which I also happen to be using.

commit 2610b4536f73493587e4a5a38e01c9961fcabb96

backend: Rely on libX11 initialising threads
Although they were definitely made with good intention, unfortunately they don't play well with the current state of NVIDIA libGL and cause an immediate crash. For now, I've settled on calling XInitThreads in totem again. But it would be better to solve the race condition that calls XInitThreads to be called too late. It seems like this would be happening for anyone using the NVIDIA proprietary driver, but I am not certain on what exact conditions cause this. |

Totem crashes (most of the time) when opening a video file. When it does crash, it crashes before playing the video at all.
It doesn't crash often when being run under gdb, profilers, or other utilities that may slow down execution. That indicated it may be a threading issue or race condition, and after digging deeper the issue is evident from the assert message.

backend: Rely on libX11 initialising threads
Although they were definitely made with good intention, unfortunately they don't play well with the current state of NVIDIA libGL and cause an immediate crash. For now, I've settled on calling XInitThreads in totem again. But it would be better to solve the race condition that calls XInitThreads to be called too late. It seems like this would be happening for anyone using the NVIDIA proprietary driver, but I am not certain on what exact conditions cause this. |

main: Rely on libX11 initialising threads
commit 2610b4536f73493587e4a5a38e01c9961fcabb96
Author: Bastien Nocera <hadess@hadess.net>
Date: Wed May 4 11:37:37 2022 +0200
backend: Rely on libX11 initialising threads
Although they were definitely made with good intention, unfortunately they don't play well with the current state of NVIDIA libGL and cause an immediate crash. For now, I've settled on calling XInitThreads in totem again. But it would be better to solve the race condition that calls XInitThreads to be called too late. It seems like this would be happening for anyone using the NVIDIA proprietary driver, but I am not certain on what exact conditions cause this. |
