[dev] Nag New Task Problem

[marvin_01]

Hi all,
I have following NAG problem using HEAD version. Everything was fine 
until I started to play with multiply tasks lists. Suddenly I was unable 
to store new tasks with notification "task not found" after "commit 
task" action. I found that if I create more than only one task list and 
set one as default task list than this one become unable to store tasks 
to, but I can store tasks to the rest of task lists. Furthermore during 
return to the task list I can see that taks_id is null! There are no 
error messages neither log records.

Does anybody have any fix?
