In 'winecfg' (or 'wine winecfg')   [ is this 'wine-binary' or 'wine-winelib' ? ]

if I select:

I have a full stacktrace. (cannot attach files here? )

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
If Applications -> Default Settings -> "Win95 or XP" 
it does not crash, but I cannot run winecfg anymore.
It only returns to stdout:

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  1 (X_CreateWindow)
  Serial number of failed request:  13
  Current serial number in output stream:  14

It works again after removing the new settings from '.wine/user.reg':
