Comment 1 Milos Kleint 2008-07-15 12:37:20 UTC 
something wrong in your installation? all schemas shall be included in the internal catalog I think.
Comment 2 ris 2008-07-15 13:43:10 UTC 
Can't reproduce it.

The start page displays "Cannot connect to internet"

No exception is thrown.

Comment 11 Lukas Hasik 2008-07-21 09:45:48 UTC 
seems as duplicate of 139937. I'll leave it open for evaluation.
Comment 12 Antonin Nebuzelsky 2008-07-21 10:27:30 UTC 
Probably because of upgrade filesystem dtd 1.2.
