I think I killed the twilight zone bug!
summary_select_node() flushes GTK events in order
to be able to center the view. But this also
flushes keypresses like Ctrl-Alt-U, so this can
call summary_show from summary_select_node (itself
called from summary_show, etc.). And the summaryview
has to be unlocked in this function. So just locking
while processing GTK events, and bailing if locked,
should fix it.
Fixes bug #927 (SIGSEGV during Update Summary)
