I get this crash or similar all the time now (aka often), with this
build, but no, I don't have a recipe.  If I can figure out something
about the context I'll let you know, but feel free to leave the bug
closed in the meantime.

No idea whether it is related, but I also have *lots* of frame
sizing problems with this build (much more than before, where
since 2014-10-20 I've had sizing problems with thumbnail frames
and some with normal-size frames).

I see that there is a lot of bug-list correspondence between
Martin and Keith these days about some frame size things, and
I'm hoping that with a little luck some of my frame problems
will go away by the time I get a new Windows binary, thanks to
their efforts. ;-)

Again, no idea whether my recent frame problems have anything to
do with these recent crashes.  Just thought I'd mention it, in
case someone sees something similar or it rings a bell.
