I have taken a look at the backtrace and it shows that the crash is in
Apple WebKit when it tries to initialize the JS VM (the dictionary popup
is apparently implemented using a web viewer).  I've converted the
backtrace to plain text and attached it to this bug report.

Yes, that'd be helpful.  If anyone has a detailed recipe to reproduce
this bug, feel free to comment.  For know, I've tagged the bug as
unreproducible.
