--- Comment #21 from Nikolay Sivov bunglehead@gmail.com --- Hi, Juan.
This is a patch to source code, you can't patch a binary dll file with it. Currently we are in preparation for next major Wine 1.8 release, this fix won't be included in it, but I expect next release after that (in several weeks, first Wine in 1.9.x series) to be fixed, and playlist will be loaded properly. Don't worry, you'll be notified when it's done.
