Comment 1 Jasper St. Pierre (not reading bugmail) 2013-11-09 13:55:42 UTC

Quite likely. Any hints for reproducing it?

Comment 2 Andreas Nilsson 2013-11-11 10:04:37 UTC

Happened today again. Here is how I did it:
* Chatting over jabber with a friend, via the popups in the bottom of the screen.
* Getting back to a browser window (Firefox) again, while chat is going on.
* Firefox windows won't take input. The flash video in Firefox was still playing as regular with sound and everything.

Only top bar (app menu, clock menu, system menu) taking input. Not activities, and not the bottom bar. Tried to shut down via the system menu. Shutdown dialog popped up, but when I pressed the "Power Off" button, nothing happened.

Comment 3 Andreas Nilsson 2013-11-15 13:43:29 UTC

I did a recording: https://cloud.gnome.org/public.php?service=files&t=774d6ee5e09f480ccbd1376e44f4dd37

Lockup is around 1:27

Comment 4 Andreas Nilsson 2013-11-15 14:10:51 UTC

One more video, triggering the lockup pretty fast https://cloud.gnome.org/public.php?service=files&t=fc755e8d8b2257f82b77d633edf46364

Comment 5 Andreas Nilsson 2013-11-15 14:57:46 UTC

messageTray: Prevent reentrancy issues in _updateState

The methods we call in _updateState may not be reentrant, so make
sure that we never get into a situation where _updateState, through
some crazy chain of events, never calls itself.

Comment 7 Florian Müllner 2013-11-15 15:58:46 UTC

Review of attachment 259920 [details] [review]:

Not the most elegant fix, but considering the complexity of the message tray code and the potentially severe effects of failures in _updateState(), doing this as safety net looks like a good idea.

The commit message needs a little fix though ("make sure we never get into a situation where _updateState never calls itself" - au contraire, it's about preventing _updateState() from calling itself)

*** Bug 712199 has been marked as a duplicate of this bug. ***

Comment 9 Mathieu Bridon 2013-11-18 10:17:48 UTC

FWIW, I'm currently running with Florian's patch from comment 7 applied on top of gnome-shell-3.10.2-1.fc20.x86_64

At work, I used to have to restart the shell about half a dozen times per day due to this bug, and since I applied the patch, the problem didn't happen once.

Could this get into a 3.10.x release, so that distros can have it in an update?
