Description vedant agarwala 2013-08-23 21:26:34 UTC

If an APG does not contain the "Playlist duration" constraint, nothing happens when the run APG button (blue right arrow) is clicked. Also, if I try to a "Playlist duration" constraint like "longer than" 2 minutes (so that this is a redundant constraint), nothing happens.
By nothing happens I mean a statusbar is shown (probably the "generating playlist" statusbar) for a split second and no change is made to the playlist.

Reproducible: Always

Easy workaround: select a long duration and select the option "longer than".

But, comfirmed on current git, v2.8.0-458-g53f0980, and this is a regression as it used to work before.

Fix long-standing bug: APG returns empty playlist

Well, that was dumb.  Added a sanity check where if the suggested
playlist size is 0 (which means "I don't really care what the playlist
size is"), then just go with whatever the non-zero size from the
previous iteration was.
