Ys: The Ark of Napishtim (Ys 6) silently exits, no backtrace or additional
console ouput, when playing the in-game videos with Wine 2.5 (2.4 works).
Clean 32-bit prefix, winegstreamer set to disabled and winetricks amstream
quartz for working video playback. Start a new game and once reaching the
opening video you hit the crash.

Bisecting returns:

Reverting the commit on wine-2.5 stops the crashing and videos play normally.
