Endless loop if no playable track is in the tracklist.

During development of PR #1376 I run into this issue and fixed it in #1376.
I think this issue is independent of #1376.

I revert the fix in #1376 and create a new pull request with the fix.

Sorry, with 75a365e the issue it is not reproducible.

[dublok]

It is reprocible if consume is false.

This sounds quite related to #1221.

Fixed by PR #1454.
