Hm. Evidently you are dealing with a bug that we fixed in 7.2.

Sorry to hear that; because even if someone were to go to the trouble
of extracting a back-patchable fix from 7.2, you presumably couldn't
update your machine with the fix.
I recommend finding the necessary political leverage to cause an update.
Perhaps reading the 7.2 release history would help light a fire under
your sysadmin. We fix a *lot* of bugs in every release; this one
is honestly not the worst bug you will find in 7.1.
