[tigre (tigreofearth)]

got the same bug on elementary OS beta 1 Freya after opening spotify

[Thomas Citharel (tcit)]

Same as above

[Kauliukas (6d61696c)]

I can confirm tigre (tigreofearth) observation that crash is somehow related with Sportify.

The only difference is that I got the crash after browsing Spotify for a longer time and not immediately after opening it.

[Thomas Citharel (tcit)]

I also got this crash at random times after using spotify some time.

[Thomas Citharel (tcit)]

Also, Spotify (sometimes ?) skips to next song when this happens.

[Samu Nuutamo (carbon)]

I can frequently reproduce this crash with the following steps:

1. Open an artist page with lots of content (like Bruce Springsteen)
2. Start playing a song from the "Popular" section
3. Start scrolling down furiously using the mouse wheel
4. Wingpanel crashes at some point

[Radek Krg (radek-2)]

same here, crash while playing spotify, no other special circumstances noted

Would be really helpful if someone marked the bugs on bountysource as in progress, I just spent time fixing the same bug..
