amarok freeze when playing from time to time

[Sheng Yang]

After recent upgrade(Kubuntu 8.10, at most within two weeks), I found amarok would randomly freeze keyboard when playing musics.

Only keyboard freeze, and amarok cpu utilization is in normal status. The only way to survive is open System Monitor by mouse and kill amarok. At the time, the music is still playing and everything seems OK except keyboard.

By the way, I am using global shortcut very heavily, which maybe one of reason. I can't find a way to reproduce it realiable, and I encounter this about once a hour.(maybe got nothing to do with the time.)

UPDATE: This freeze happened from time to time regardless of keyboard operation. Just After freeze, OSD didn't disappear and if you use global shortcut, the keyboard would be freeze as well. Backtrace from gdb attached in latest comment.

I found it's may related to music filetype.

This situation mostly happen when playing FLAC file. Seems like some racy problem is shown due to heavier load than mp3.

Seems no related to the music type, play MP3 also caused trouble.

Maybe related to OSD display, almost everytime keyboard freeze, OSD display is showing. (so if I didn't see OSD disappear, I would know that trouble come...)

OK, I have suffered this 4 times in 2 hours' listening...

OK, now somebody can take a look? Attached GDB backtrace information.

I've changed the amarok-engine to yauap, same result, but maybe not that frequent.

Found it was resolved in recent upgrade. Thanks.
