Comment 1 Matthew Barnes 2008-07-08 15:00:55 UTC 
Accessibility related.  Is this reproducible at all?
Comment 2 sangu 2008-07-09 03:48:38 UTC

> Accessibility related.  Is this reproducible at all?

Your comment is right.  After disabling Assitive Technologies, this problem
doesn't happen.
Comment 3 Orlando Arias 2008-08-05 18:38:43 UTC 
On my system (patched to latest updates) Evolution does not crash when switching to calendar mode (from any place, I might add), it just freezes on the spot and I have to SIGKILL it.
Comment 4 Matthew Barnes 2008-10-20 18:59:40 UTC 
Crash reported upstream at [1].  I can also easily reproduce the crash with Evolution 2.24.0 and accessibility turned on.

Comment 5 Matthias Clasen 2008-10-21 05:05:34 UTC 
I've put a patch into at-spi to make it survive this kind of abuse, but really, evo should be fixed to emit this signal properly.
Comment 6 Matthew Barnes 2008-10-21 15:30:00 UTC 
Upstream bug has a patch that comments out the bad signal emission.  Oddly, the code causing this crash has been lurking in Evolution since 2003.
