for some reason, I cannot reproduce the above behaviour at the moment, so let's leave that bug alone for now. (For the record, it was in an unthreaded build. Maybe gnome-keyring had something do to with it.)
I was wrong, gnome-keyring is innocent. I just did a new unthreaded build "--with-gnome=no", only to discover that the behaviour described above had reappeared. This is a gdb session containing the output of "balsa -D", where I entered my password twice before hitting cancel (and thus triggering the segfault):
