I'm investigating several PIX/ASA related difficulties with rancid at the 
moment, and having moved to 2.3.2a8 rancid and clogin I also see this.  I 
started to reply to this thread but got bogged down in looking into other 
problems, but here's what I'd written on this particular issue:

Is this the "Written by rancid at ..." line you are seeing?  Having moved 
to using clogin and rancid from 2.3.2a8, I see this too: it seems to be as 
a result of using the output of "more system:running-config" specifically, 
which is relatively new.  A simple patch fixes it (applying by hand should 
be trivial, look for line 1551):

Here's some sample .raw output:
