It's possible that the application installed an exception handler to handle a
segfault and display the dialog box. This won't show up in a log file without
+seh. It's also possible that you're correct, I don't know.

The hope was that one of those debug channels would give us an indication of
where the problem occurs in the log file. E.g. if it's a standard user32
MessageBoxA() dialog box, then we should see that on the +msgbox channel in the
log file.

It should apply, but I don't know if that's useful. Wine's dmusic
implementation is basically completely wrong. We just need to find out which
wrong bit is responsible for this particular error, and fix it :)
