--- Comment #16 from Keith Dunwoody keith.dunwoody@gmail.com --- I doubt it's that patch, since that looks like the 16-bit library. However I believe the Journeyman Project issue should be fixed by https://github.com/wine-compholio/wine-staging/blob/master/patches/avifil32-... -- untested, but description matches my observations.
