amarok crashed with SIGSEGV in ThreadWeaver::Job::execute()

[Steve McGrath]

Binary package hint: amarok

Amarok crashes every time I try to activate dynamic mode. Once it does this, it will crash on startup every time, until I remove it's configuration from ~/.kde.

I haven't been able to make Amarok work since the first 2.2 beta version (2.1.85?) hit the Karmic repos.

I previously filed another bug about this, but this is the first time I could get apport to catch & report the crash.

Is this still an issue in 9.10 final?

[Steve McGrath (smcgrath23)]

Indeed. Dynamic mode causes Amarok to crash in the following circumstances:

1) Empty Playlist. Enabling dynamic mode crashes Amarok while generating the playlist.
2) Exisiting Playlist. Enabling dynamic mode and clicking "Re-populate" crashes Amarok while generating the playlist.
3) Existing Playlist, already playing. After enabling dynamic mode, Amarok crashes when skipping to the next track, as it attempts to select a new dynamic track for the playlist.

Fixed in 2.2.2 in Lucid
