Operating System: Linux 3.19.8-100.fc20.i686+PAE i686
Distribution: "Fedora release 20 (Heisenbug)"

-- Information about the crash:
- What I was doing when the application crashed:

Sorry, but my English is not very good.
At the start of the player segmentation error occurs. The exact causes of a loss to name, but it is likely that the error occurs because the Intel graphics driver.

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
