crash while checking mail

Hello,

I quite often get the following situation - I see (in a biff) that
I have a new mail. The same folder is selected in M (M does
not see new message(s) yet), and I press F5 (Check mail).
Then M takes 100% CPU and starts to eat memory. Sometimes
I am quick to switch to console from where M was started and
press Ctrl-C, sometimes kernel kills M (after a few minutes, during
this time X is unresponsive).  I suspect it happens when M was
already checking for a new mail and I pressed F5. Today I ran
M in gdb and was able to Ctrl-C (interrupt) M and take a bt:

Program received signal SIGINT, Interrupt.

I see a few repeating SendIdleEvents, is it normal?
