I don't believe I have ever heard of wrinkled titanium curtains on an XK or any other similarly equipped camera like the Canon F-1, Nikon F, F2, F3 and Pentax LX.
Titanium curtains can wrinkle. A friend of mine, while trying to remove a roll of partially-exposed film from his Nikon F in the dark, stuck his thumb right into the shutter. The second curtain took the brunt and was big-time wrinkled. He had a repair tech check it out, and while the shutter looked like hell, it still operated within tolerances.
Take a look at the KEH website. There are a few wrinkled curtain Nikon F's on there right now.
