There was an *old* RPM bug (RH9?) that was caused by a corrupted database that caused rpm to hang.  You can try the verifydb and, if necessary, the rebuilddb.  On the other hand, the last item reported by strace is a futex which says rpm is waiting on something.  Check to make sure that there isn't another copy of rpm running (actually also probably hung and waiting on something else).

Cheers,
