--- Comment #1 from Sebastian Lackner sebastian@fds-team.de --- If you suspect this is a Wine Staging regression it would be more useful to compare Staging and development versions with the same version number. Could you please check which versions are affected exactly? If it also affects recent development versions, this bug should be moved to the "Wine" product here on bugzilla.
Also, please attach the full terminal output, not just the crash itself. This might give a hint what exactly is going wrong. If multiple games are affected, could you please give some more examples? If possible also try to find a way to reproduce it using a demo version or freely available game.
Two other remarks:
* Staging includes various experimental features (for example CSMT). If you have enabled such features (in the winecfg Staging tab), please try to disable them for testing purposes.
* Based on the terminal output you probably did not set the WINEPREFIX correctly. In your case it should be set to "\home\werner.winebak", otherwise registry entries and dependencies will not be found correctly.
