[nag] Error when finishing a task via checkbox

[Sven Flossmann]

hi,

I'm getting the following error, when I try to finish a task in the 
tasklist via the checkbox:

Fatal error: Call to undefined method PEAR_Error::get() in 
/var/www/www2.flossmann.net/horde_080912/horde/nag/lib/Driver.php on 
line 345

The corresponding code segment is below.

What I'm not understand are the following two things:
a) Why is the tasked moved? (Where shall it be moved to?)
b) Obviously, an error happend (PEAR_Error). Why is the get() method not 
defined?

btw: If I complete the task via edit -> mark it compete -> save ... then 
it seems to work.

Thanks,
     Sven

PS: NAG V2.3, Horde V3.3
