My guess is that the older version of RC you are running is not happy with the upgraded PHP version - hence the "deprecated" warning. Since the current stable version is 0.5.2, it might be time for an upgrade in RC as well.

Platform:  Debian 6.0 Squeeze i386

Symptom:   Immediately after RC login and seeing the mailbox view I am
instantly redirected back to the login page.  This occurs via http and
https, with or without https redirection enabled.  I did not have this
problem immediately after the Squeeze upgrade when I tested all apps on
the server to make sure they were all working.

Related information:

I can't recall the exact details, but an issue unrelated to Roundcube
forced me to remove and reinstall one of the php packages on the system.
 I'm guessing this is the source of the problem.  There are 234 php and
related packages in Debian 6.0 and I have no idea which one(s) I need to
reinstall to fix this problem.

Any help would be greatly appreciated.

Thanks.
