You were exiting, it looks like. If so, you can maybe just live with
it; AFAIK it doesn't actually happen until well after all user data is
safely tucked away in files.
We are _not_ kidding with that warning. There are many known bugs in
various versions of Motif, here are two of them:
Motif is the X11 version of the Gnus torture test: if there's a way to
crash, Motif will find it. With the open source release of Motif, it
seems like a good idea to collect all Motif-related issues in one
You should also look in your OS's section, as it may not be Motif's

This is known to happen with Lesstif version 0.93.36. Similar
backtraces have also been observed on HP/UX and Solaris. There is a
patch for Lesstif. (This is not a solution; it just stops the crash.
It may or may not be harmless, but "it works for the author".)
Note that this backtrace looks a lot like the one in the next item.
However, this one is invulnerable to the Solaris patches mentioned there.
Frank McIngvale <frankm(a)hiwaay.net> says:
Ok, 0.93.34 works, and I tracked down the crash to a section
marked "experimental" in 0.93.36. Patch attached, "works for me".
