--- Comment #4 from lehmannwer@gmail.com --- The folder "/home/werner/.winebak" is a backup copy. I do also have a folder "home/werner/.wine" freshly generated by a "winecfg" command after the installation of i386-wine-staging 1.9.14. So cding into the .winebak folder and executing a "wine" command should use the configuration from the ".wine" folder. At least that did work when ".wine" was freshly created with wine 1.8.x. However, this does not seem to work with kmquake2. I really had to copy the Quake2 folder from .winebak to .wine and the it worked again with staging 1.9.14. But when moving the Steam folder from .winebak to .wine, the game TF2 would still crash the same. Also under Steam, the installed "Just Cause" Demo with 1.9.14 will not load, as it did with staging 1.9.3. I remember trying 1.9.10 and 1.9.11 staging and one of the two versions as devel-versions only and I had the same problem. I have not enabled the special features of staging either. Take my word for that 1.9.3 staging was the last version where TF2 and also Just Cause Demo ran fine. I have attached the terminal output of starting Steam, TF2, Just Cause Demo (with aborting because it would not load) and Gladiators Online, which did work, even from within .winebak.
