Description Matthias Clasen 2012-06-15 21:57:01 UTC 
In bug 663256 there is a patch that adds a 'Screen Reader' menu item to the gnome-shell a11y menu. When using that item to turn off the screen reader again, I get a segfault in cally:

When I started to look at this I was able to reproduce the bug. Working on this I found a solution to bug 675183 (pushed to git master). Now Im not able to reproduce this bug, so I assume that the crash was caused by a key event listener not properly uninstalled.

Matthias, could you confirm that the bug is solved?
