uucico trashes messages

I seem to fairly frequently get UUCP messages with uucico garbage strewn
through them.  I'm attaching an example of such a message below.  Because
of the nature of the garbage, it looks like a uucico problem.  Also, I've
seen it happen with all of our UUCP partners, which leads me to believe
that it is my uucico which is doing this.  We are running Eunice here, so
I am wondering if its uucp software is causing the problem.  Has anybody
out there seen this kind of thing?  Any suggestions what to do?  (If it
involves poking around in the guts of uucico I can't do it; we don't have
source.)  Thanks in advance.

Edited copy of trashed message follows:

rticles were very abbreviated, but tried to give all the
essentials in a clear way.  I would be interested in your comments.

I have seen this happen when uucico can't open the AUDIT file for writing
out debug messages (those lines which magically appeared in your mail
messages).  

What's happening is that uucico, when started up in slave mode, always 
attempts to open $SPOOL/AUDIT (/usr/spool/uucp/AUDIT) as stderr.  
This is attempted by first closing stderr, then doing an fopen on
AUDIT.  Too bad that fopen's return code is not checked!  So, when
the data file is later opened, it returns file descriptor 2, and
all debug output being written to stderr gets into the data.  (Some
versions do an 'freopen' call instead of the flose/fopen pair.)

The no-source fix is to make sure that $SPOOL/AUDIT exists and is
writable by user uucp (or whatever user name your copy of uucico
is setuid'd to).

The proper fix is to modify cico.c to check the return code when it
opens RMTDEBUG.  And then to take appropriate action if it failed.
