Fixed in CVS, xmlschemas.c revision 1.140.
The bug: the processor missed to convert the NULL value to an empty
string, which is expected by xmlRegexpExec(). As we gave it a NULL,
it returned an API error, resulting in the error reports you have seen.
Actually both instances triggered this error with the current CVS HEAD
code.

Thanks for the report!
I added your examples to the regression tests.
