--- Comment #2 from Konstantin Kharlamov hi-angel@yandex.ru --- So, I debugged it through inserting prints, and I can tell the error is happening on this line
https://github.com/wine-mirror/wine/blob/16e73be10d940c9c04101a47687a6f8a385...
this is some kind of a callback, and it's apparently throwing an exception, because when it happens, prints inserting a line below won't get executed.
With that said, I am as clueless regarding the cause as I was hours ago.
