Not me.  Nyah, nyah.

I've recently seen exceptions too when trying to run Win3.1 (and DOS,
but I'm not sure that's supposed to work) applications.

Sucks, I wonder what can be done in general about that.

Just starting the application causes it to segfault, so one approach
could be to find a buckload of Win3.1 programs and create a testsuite
that just tries to run them and declare the test a success if they're
still running after 10 seconds.

No, seriously :-).

You might want to file a bug report?
I think the core developers have much more interesting things to do
besides fixing bugs, so the best bet is probably to create a bug
report (with URL to the app) and wait for a developer to become bored
or hungry for a small victory.
