[Rock-dev] clean shut down of a task fails if there is a pulled connection

[Alexander Duda]

It seems that all tasks which were previously connected to an other task
via a pulled connection fail to do a clean shut down if the other input
port was already deleted.

Does anyone knows how to solve this? I would be very annoying if the
tasks have to shutdown in the right order.

Thx Alex
