Description of problem:
Occasionally (2-3 times per week) evolution hangs with 100% CPU usage.
Attempts to exit leave an open message box "Evolution is now exiting..."

It is configured to scan 2 IMAP/SSL accounts (on myrealbox.com) and
one POP account, plus several RSS feeds.

It stays hung for hours until killed.  Upon restarting evolution,
behaviour is normal.

This would be a mere annoyance except for the CPU saturation, which
interferes with other processes.

Sample strace output in Add'l Info section below.

If grabbing a core dump would be helpful let me know.

Version-Release number of selected component (if applicable):
evolution-1.4.5-7

How reproducible:
Sometimes

Steps to Reproduce:
1. unknown, but using multiple secure IMAP accounts in my case
2.
3.
    

Additional info:

Strace output for the busy evolution process looks like the following,
infinitely repeated:
