"Error 500: Internal Server Error" with version 1.5

Yes I turned on the debug and see that there is a memory poblem.
then give more memory 64M, still the same error.

But this problem occured suddenly. While everything is great then after some little calendar operations I got this error.

What cuses this error?

Wrong formatted calendar entries? or..

I'm trying to delete last added calendar inputs.

Non-stable internet connection caused this.

I move objects to a temporary workspace and delete the old workspace, then create again.
