This might be fixed in git already.

Comment 2 Sven Krohlas 2010-04-30 13:04:23 UTC 
I don't think it's a dupe of bug 227599.

@reporter: can you please restest with 2.3.1 beta 1?

Comment 31 Myriam Schweingruber 2010-07-24 02:15:22 UTC 
Martin, thank you for the backtrace, but it is not useful, as you don't have debugging symbols installed for Amarok. 
Also, as you can see from the long list of comments this bug has already been  confirmed several times for this version, no need to provide another backtrace, since they all look the same anyway.

Comment 34 MHildebrandt 2010-07-26 13:35:55 UTC 
Now we´re getting forward, I think. 
I´ve installed 2.3.1 from the Suse repositories (KDE Buildservice) and started Amarok from the command line with -d -nofork switches. 
After scanning about 48% of my 377000 files within about 2 hours the process became _really_ slow so that the next 5% took more than 48 hours. (I was away for the weekend and let the machines work.) When looking at the command window I noticed a lot of messages about index positions of playlists and 100% processor utilisation by amarok. 
A scan of the serverdisc (attached by NFS3) showed my 7452 M3U playlist files that where left in the MP3 directories. I´ve put those playlist files away, restarted the Amarok collection scan last night and was very happy this morning when the scan flawlessly had worked and I could use my collection again.
Looks like the many M3U files have crashed Amarok before. (That I have no use for anyway.)
If anybody is interested I can send a RAR with the M3U files....
Comment 35 Myriam Schweingruber 2010-07-28 19:15:46 UTC 
Can somebody using current git reproduce this bug? I can't.
Comment 36 pacificprince 2010-07-28 19:20:31 UTC 
I can't either. I tried deleting all the playlist files from my media collection and amarok still crashed while scanning the library.
Comment 37 Myriam Schweingruber 2010-07-28 20:00:37 UTC 
pacificprince, you misunderstood what I said: I can't reproduce this bug with current Amarok 2.3.1-git, and I am looking for somebody being able to reproduce it with the latest development branch.
Comment 38 simon 2010-07-28 23:40:38 UTC 
i just rebuilt current git, started a full rescan which finished without errors.
So it seems this is fixed now as i could not do this when i confirmed this in may. Back then i needed to patch out support for playlist scanning to get my collection working - was there a specific change? 
Anyway thanks a lot.
Comment 39 Myriam Schweingruber 2010-07-29 00:41:48 UTC 
Simon, thank you for the feedback. There were quite a few changes in git since May indeed :)
