Possible bug in TRAMP?

I'm running the carbon2 CVS branch of XEmacs on Mac OS X. (Andrew Choi requested that bugs relating to carbon2 get reported to c.e.x, but I have also seen this problem on Linux, so it seems to be a more general XEmacs problem. That's why I'm posting here.) TRAMP (package version 1.22 from sumo) is unable to find files. I get lots of messages like this: itimer "with-timeout<5>" signaled: (void-function with-timeout-handler) and then: Invalid state: Bogus value for `default-process-coding-system', nil Anybody knows what's going on, or can help me debug it?
