In general, questions about particular log messages are really
hard to answer without knowing what app is involved, and
without having a copy of the app to try.
And in particular: when you file a bug, e.g. http://bugs.winehq.org/show_bug.cgi?id=30949
and then make a forum post or email or chat about it,
please for goodness' sake include a link to the bug. Otherwise
you're doubling the amount of work people have to do to answer your
questions.
