Hmmm, interesting... the system is not truely locked up, but perhaps
it's now unable to launch new processes, or something like that.  (It
would be interesting to know if an instance of "htop" running on another
console continues keep running even after the segfault, for example.)

(It might be worth double-checking to make sure -- if for example [Byour
follow-on attempts to run "ls" and "htop" also show up as segfaults in
the log, that would certainly tell you something.)

(The distinction may not matter in the end, but off hand I'd suspect the
hardware fault [or whatever it is] is causing both the mutt segfault and
the other symptoms you are seeing.)

Anyway, good luck tracking it down...
