Re-Logging in / "Attempt to free unreferenced scalar"

Hi out there,

having installed RT 3.2.0 with Red Hat 9 Shrike, Apache 2.0.50/mod_perl2,
Sendmail 8.12.8, Perl 5.8.3 I am still running into problems,

(1) Everytime a web browser “touches” the site, tail -f /var/log/messages
will produce a whole bunch of messages like this:

Jul 12 13:49:05 salvador RT: Attempt to free unreferenced scalar: SV
0x96e7c84 at /usr/local/rt/share/html/Elements/Quicksearch line 24.
Jul 12 13:49:05 salvador RT: Attempt to free unreferenced scalar: SV
0x9637474 at /usr/local/rt/share/html/autohandler line 24.
Jul 12 13:49:07 salvador RT: Attempt to free unreferenced scalar: SV
0x96e9f20 at /usr/local/rt/share/html/autohandler line 24.
Jul 12 13:49:08 salvador RT: Attempt to free unreferenced scalar: SV
0x971bea4 at /usr/local/rt/share/html/Elements/SelectMatch line 34.

I don’t know if this does any harm, but I’d like to know what it means
anyway…

(2) After I have logged out and then in again (same user or not, no
difference), RT is kicking me out and showing the login screen every time I
try to call upon a menu. Only closing down the browser on the client machine
and restarting it will solve the problem.

What’s going wrong? Sorry if it’s something simple, but I’m an expert
neither in Perl nor Apache.
Thanks to anyone trying to help.
