Summary: Amarok crashes while generating dynamic playlist

Status: RESOLVED FIXED    
Severity: crash

Sentry Crash Report:

Description Alex LaHurreau 2012-02-06 23:27:26 UTC 
Application: amarok (2.4-GIT)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
I tried several times to generate a dynamic playlist with the following components: match all of (and):
! artist:"a"
! artist:"b"
partition (50/50) of the following:
  last.fm similar artist
  if-else sequence: (!playcount:>0) or (!last played:>365d) or random

The first few times, Amarok crashed while editing the playlist configuration. (I believe that the partition values were all zeros.) I deleted all of the subcomponents, and recreated it from scratch, and was able to create the playlist. I attempted to regenerate the playlist, but the process got hung up. (Presumably the request to last.fm got lost in a black hole.) I aborted that attempt, then tried to regenerate again, leading to the crash that I am reporting now.

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Aborted

Comment 1 Alex LaHurreau 2012-02-06 23:33:01 UTC 
I was able to recreate the dynamic playlist after restarting Amarok, and was able to generate a playlist successfully without crashing.
Comment 2 Myriam Schweingruber 2012-02-09 21:21:49 UTC 
In other terms, this crash is not reproducible? Also, why do you compile from 2.4-git? The current branch is 2.5...
Comment 3 Alex LaHurreau 2012-02-19 15:12:08 UTC 
I was running with an old build. I cannot reproduce this bug with 2.5, so I believe that it is resolved in the latest version.
Comment 4 Myriam Schweingruber 2012-02-20 12:17:04 UTC 
Thank you for the feedback.
