The UDP samples crashes if no data is received and recording is active.

To reproduce:

  1. Launch pymepixviewer
  2. Start recording data (without actually receiving any)
  3. Stop recording after a few seconds
  4. Start recording again
  5. Stop recording --> Now the GUI hangs

This seems to be an edge case and happens only if the udpsampler buffer is empty while recording file should be closed.
