This is impossible to create new or open existing project in WinterMute Engine
(game engine), the engine crashed with error:

X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  3 (X_GetWindowAttributes)
  Resource id in failed request:  0x3201163
  Serial number of failed request:  51374

libxcb: WARNING! Program tries to lock an already locked connection,
        which indicates a programming error.
        There will be no further warnings about this issue.

The problem exists since wine 1.1.36

I'll run regression test later
