not outside the realm of the possible,... but I wouldn't expect it to
cause only a single program to crash, and ALWAYS with the same set
of clicks/keystrokes, without fail. after installing a ton of
-debug packages and watching it in the debugger, it always segfaults
at the same place, and for a given set of actions with t he same
stack trace (the trace varies depending on which actions I did, but
for a single set of actions its always the same).

In fact, it dies in malloc.c, after a call from (I think it is named)
dv_freep or something ending with "freep", making me think that the
pointer being freed has been hosed (its not null), or something has
walked all over the malloc chain's bookkeeping.
