It seems that the PA backedn of xine is passing invalid arguments to
one of the libpulse API functions, which then returns PA_ERR_INVALID.
Any chance you could debug this?  i.e. find out which function it
exactly is that returns the error and what the parameters are that are
passed to it?

should come into play here.

Looks a bit like a memory corruption issue to me.
