Thanks for the report! The whole dathasloginevt mechanism is IMO too clunky
and unelegant to go ahead with, I wouldn't be surprised if there are other bugs
lurking there. Since the original authors seems to have retired from the patch
(I've only rebased it to try and help) I am inclined to mark it as returned
with feedback.
