I should have checked bugzilla, sorry about that -- thanks for the info,
though.

More info on this problem.  I have found that the problem only happens
if I do the following: if I select a message, then click on the window
with the text of the message, THEN click on apply filters (or Ctrl-Y),
then things hang up.  In this situation nothing happens when I click on
any other message or folder -- all I get is a "Keeping Connection Alive"
and the progress bar bounces back and forth.  First, I tried gdb with
the binaries from the Ximian snapshot RPMS -- I actually got a SIGSEGV
in this case (I let it sit there in the "hung" state for a while) -- but
there were no debugging symbols in the binary and there wasn't much
information. Next, I grabbed the latest CVS source and compiled it and
ran a gdb and got it in the hung state.  I waited for quite a while to
see if it would SIGSEGV again for me, but it wouldn't.  So I Ctl-C'd it
and did the backtrace, attached below.  At the beginning of the
following, I did a Ctl-Y (after having clicked in the message text
window), then I tried to click on other messages a few times, waited for
a while, then did the Ctrl-C:

Hope this helps, please let me know if I can help with any further
debugging.
