Hi,
after upgrading from 15.10 to 16.01, the trackster visualisation tool is
partly defective. It can successfully show e.g. GFF tracks, but after
adding e.g. BAM track nothing is shown. The only suspicious debug output
I could get when loading non-working-track is:
galaxy.webapps.galaxy.api.datasets ERROR 2016-03-15 11:44:38,853 Error
in dataset API at listing contents: Expected bytes, got unicode:

Any help to solve this problem would be highly appreciated!
many thanks
