I don't get a crash, but the dialog doesn't see a pcg file, even when it's in the directory. I used one from http://tritonhaven.com/downloads/pcgs.html
Yes, that's another issue with Wine, the default file type filter is not correctly applied when creating the file open dialog. In order to open the PCG-file you have to select "All files (*.PCG)" from the drop down menu, even though it's already selected. This works fine on Windows without the need to re-select the file type.
