Re: [Evolution] Very frequent Evo freezes

[Not Zed <notzed ximian com>]

Its pretty unlikely multiple threads are accessing gtk/etc, we know its
not thread safe, so are very careful about using it (as much a mess as
it makes of the code).

Is anyone else experiencing this?  I'm definetly not getting it (yet) -
I very infrequently update gtk/etc though.

gdb seems to be playing up too, perhaps try cvs gdb?  Not really sure
...
