SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***


STEPS TO REPRODUCE
1. Start amarok playing an icscate https stream
2. Wait for an unspecified amount of time. We are talking hours or days
3. Notice that on thread of amarok is using 100% CPU

OBSERVED RESULT
100% used by thread ThreadWeaver::T (use top and press "H" to see threads) 
The stream still plays fine and what I think is the player thread uses the normal 10-15% CPU

EXPECTED RESULT
No parasite 100% thread should run

Tried to edit my initial entry but couldn't. The stream is an icecast stream.

I'd be very interested to hear if you still experience this issue with 3.0.0
