I believe this is only happening to me when I have rhythmbox open and playing or paused (if i haven't yet played anything the crash does not occur).
Using this I've been able to replicate the crash over and over, or have it work fine with no sound in the picture. WIll test other applications with sound as well soon. Also, I've been able to replicate the problem with the nv driver, so I'm getting very sure this is not an nvidia problem at all.
I can confirm that the crash occurs only when sound is playing so this is not nvidia problem.
1. Log in as user A
2. Start rhythmbox and start playback
3. Use fast user switch applet
4. Log in as user B
5. Try to switch back to user A with fast user switch applet
6. Crash! Only the second xorg instance for user B remains, instance of xorg for user A crashes.
Please link the bug on fedora bugzilla here after creating the bug report. Thx
