New crash information added by DrKonqi

amarok (2.6.0) on KDE Platform 4.9.5 using Qt 4.8.3

- What I was doing when the application crashed:

Same as parent, Amarok sometimes refuses to start when I launch it from the Kickoff Menu. Occasionally, the crash reporter comes up.

After several tries, it eventually starts.
