I have tracked down the problem. dv1394src uses the userdata field of
its libraw1394, for quick access to its own data structures in callback
functions. Starting with version 0.5.3, libavc1394 also uses this
userdata field, for its own purposes. Ofcourse, dv1394src doesn't really
appreciate having its userdata pointer overwritten.

I have reported this issue to the gstreamer people, and filed a bug [1]
on the gstreamer bugzilla. I have also contacted the libavc1394
maintainer to get his opinion.
