--- Comment #13 from Erich E. Hoover erich.e.hoover@gmail.com --- Martin, the issues you have here should be resolved by wine-staging commit f9e86098b3136869479621e432ea0b066d217add. Would you mind updating and giving it a try?
Also, as an FYI, I have a couple other issues that I have been tracking that I intend to push fixes for once I'm done testing: 1) remove the prefix from absolute paths that don't point inside the prefix 2) mark the prefix in absolute paths and rewrite it if the prefix path changes
