Traceback (most recent call last):
  File "C:\BuildbotWorker\buildpackage_windows\build\golem\client.py", line 605, in create_task

KeyError: '0084d14d-b8ff-4d9e-86a3-f1beba9136a4'

In interface it shown warning but Golem continues computations (in logs it seems to be ok)
If not restarted immediately, computations are finished (despite the warning).
Results are shown after restart of an application, task status is finished.

Steps to reproduce:

• add a task - classroom file with small resolution 400x400
• wait for warning in interface and leave Golem running
• wait appropriate amount of time for task to be finished
• restart Golem
  -check if task is finished

\\vmware-host is a network path and I don't think we're going to support that in the near future. We should filter out unsupported paths.
