My first 11g show stopper: Purging the Recyclebin

I've run into my first issue with 11.2.0.2.  After one of my dbs was upgraded, every time I try to purge the recyclebin, I get an ORA-00600 error:

SQL> purge dba_recyclebin;
purge dba_recyclebin
*
ERROR at line 1:
ORA-00600: internal error code, arguments: [ktcdso-1], [], [], [], [], [], [], [], [], [], [], []

It doesn't matter if the recyclebin is on or off.

I have done about six upgrades and this is the only db with the problem.  I can backup this db using RMAN and restore it on another host and the error still gets generated.

I have about 43 objects owned by SYS and named WRH$* left in the recyclebin after the upgrade, but these are normal after the upgrade. Or, at least, I have these objects in the recyclebin after every 10.2.0.5 -> 11.2.0.2 upgrade I've done so far.

I can purge the objects individually to get rid of the immediate problem, but I am most concerned that this will show up again in another db.

I couldn't find anything on metalink.  I've had a TAR open with Oracle Support for well over a month and it's going nowhere.

Listener Logging in 11g

By default, the listener logging is not turned on in 11r2.  You have to turn it on by specifying:

LOGGING_listener_name=ON

in your listener.ora file.
