Resuming download doesn't always work (Linux)

[hekkup]

Command line yle-dl resumes dl with much more certainty. Qyledl seems to be more uncertain. This can be verified with several stop/restart cycles and comparing the results with yle-dl and qyledl. What's the reason for this? Anything to do with how Qt stops a process? I have no clue but this needs investigation. This may as well be a bug with yle-dl (or rtmpdump).
