while i'm investigating this you can just use paxctl -c (which is preferred over -C).
paxctl 0.7 fixes the bug.
(In reply to comment #3) > paxctl 0.7 fixes the bug. Its in the tree. I tested and its fixed. I'll wait a few days for the reporter to comment and then close this bug.
Reopen if this is still a problem.
