I wanted to report something that has been hapenning regularly (about 1/2 times per day).
There is this advertising that sometimes shows up and, unlike the other normal advertisings, this one has no sound and the player doesn't go forward. The only thing that even suggests it is an advertisement is the image that appears where the album covers normally are. Something related to a "studentatwork.be" ??? (screenshot attached).
When this appears, the player just hangs and the only workaround is exiting Spotify and turn it back on.
Other advertisements do not cause this to happen.
I am running Sportify version 0.9.4.183.g644e24e0 for Linux.
Using Ubuntu 12.04 LTS
