[Evolution] Bug#434910: evolution sporadically becomes unresponsive, uses all CPU: help debugging

[Ross Boylan]

This problem is really making things difficult for me, so I attempted to
debug it.  I have evolution-dbg installed, but something seems to be
missing.  When I attach to the process during one of its high CPU times,
I got messages that it was loading many symbols and then
Reading symbols from /usr/lib/libglade/2.0/libgnome.so...done.

Backtrace stopped: frame did not save the PC

I did gdb on /usr/bin/evolution.

Can anyone help me get something better?  The oddities I notice are
1. "Failed to read a valid object file image from memory."  Maybe this
refers to the main binary, and that's why I don't see many symbols?
2. lots of missing symbolic info on the stack.
3. "Backtrace stopped: frame did not save the PC"

BTW I'm currently unable to build from the source on my machine becausee
the build-dependencies required seem to knock out too much.
