[horde] Blank login screen after installing nag

[Lars Bjørndal]

Hello!

Until yesterday, I had a working cvs version of Horde/Kronolith. But
when I installed some more applications, I cannot log in. The login
screen says "Welcome to Horde", nothing else. If I comment out the nag
application in registry.php, the login screen is back again. The horde.log
file ends up with this lines:

Oct 03 23:35:54 HORDE [debug] [nag] Hook _horde_hook_share_init in application horde not called. [on line 1487 of "/usr/share/pear/Horde.php"]

Do some of you know what I have to do to get nag working (or at least
the login screen)?

Best regares,
