That's a problem which appeared after the last update of l3kernel.

xparse.sty (and every other package of l3packages) should use at the
beginning

\ProvidesExplPackage
{\ExplFileName}{\ExplFileDate}{\ExplFileVersion}{\ExplFileDescription}

instead of 

\ProvidesExplPackage
{\filename}{\filedate}{\fileversion}{\filedescription}

The maintainers already know about the problem. The next update will
solve it. In the meantime: change the .sty manually.
