builtins.ValueError: unknown file extension: .

appears during multiframe, multisubtask task. (more subtasks than frames) in interface several frames are shown as stuck in verifying state - are not finishing at all nor end in timeout. As a result, whole task ends in timeout. For example: Helicopter scene, Low Res, two frames, two subtasks per frame, task timeout 1 hour, subtask timeout 15 min.

Two subtasks are finished, two in verification. After time of subtask timeout passes (15 minutes), subtasks still staying in verification state until whole task timeout.

it is possible to see results of computations in second preview window, even though subtask is not finished

in subtask timeout should be included time for verification on requestor's side and added check, if this time had passed
