Thanks Ken, I'll follow up with the user with these points. My app
doesn't post keyboard events itself, but on further discussion it
sounds like the app is hanging rather than actually crashing, so the
Force Quit situation definitely could be the case.
The default key combo for Front Row seems to be command + enter, Force
Quit is command + option + escape, so they don't seem to be all that
similar. But it could be some other user error.

accidentally like this! Naturally it's not something I can
reproduce in the development environment, and seems to be affecting
just one user.
Some WAGs:
* Does your app post keyboard events? Perhaps it got corrupt data
and accidentally posted the key combination for Front Row.
* Could the user be attempting to Force Quit your app and getting
the key combo slightly wrong? IIRC, the default combo for Front Row
is pretty close to that for Force Quit.
* Actually, could your app have a key combo that the user might be
trying to invoke, but a) they're getting it wrong and hitting the
one for Front Row instead, or b) they have (accidentally?) remapped
the combo for Front Row to the one that your app uses?
* The user's system may be so hosed that the crash reporter (or
whatever has replaced it in Snow Leopard) is somehow hooked up to
Front Row instead of whatever it should be. Can't imagine how that
might happen or how you'd diagnose it.
You might have the user disable the key combo for Front Row
altogether to see if the problem goes away.
Good luck,
Ken
