Add queue watcher problem

Hi,

we’ve running rt-3.0.4 with mysql-3.23.52 and apache 1.3 (mod_perl1)
on a SuSE 8.1 box.
All tickets and users are imported from rt2 (with rt-2-to-3 v1.12).
If I try to add a watcher to a new (not imported) queue i got
the error:
group not found

the logfile contains then the following entries:
