Version: 2.3.1 (using KDE 4.4.5) OS: Linux Hi All, This is my first bug report so I will try to be as descriptive as possible. My system: Laptop : Thinkpad T500 OS : Kubuntu 10.04 Amarok version : 2.3.1 (from backports repository) I have approximately 20,000 tracks in an external hard drive (ultra-bay to be exact). I am quite sure that I have configured MySQL correctly. Some things that happened when I tried to scan my collection: 1. Amarok crashed every time I tried. If I restarted the application it would resume scanning, but it could not add over ~12,000 tracks in the collection browser (yes, I quit Amarok and restarted it to make sure the collection browser was updated). 2. I tried adding one folder at a time, but this was very tedious and the results were the same as in 1). Sometimes, when a new folder was scanned, all the previously scanned entries from the collection would disappear! 3. I deleted the Amarok folder in ~/.kde/share/apps and the configuration files. Restarted Amarok and the scanner STILL failed as in 1). 4. Ok, so I scrounged the internet and forums suggested to run the collection scanner from the command line. I got the file amarokcollectionscanner_fullscan.xml (can't remember the exact file name), put it in the amarok directory and did a full rescan. Failed again. 5. I tried deleting all the playlist (.m3u) files from my collection but this also did not seem to make a difference. Just to be clear, the collection is scanned perfectly in Amarok 1.4. Also, the Clementine music player is able to scan my entire collection without any problems. I have spent --hours-- days trying to scan my full collection. Am I missing something? Could someone please help or suggest other fixes/patches? Reproducible: Always Steps to Reproduce: 1. Start Amarok. 2. Scan collection. Actual Results: Crashes or adds less files than in collection. Expected Results: To scan and add complete collection!
The amount of files is certainly not the problem, we have people with much bigger collections. Could you please provide a valid backtrace? A crash report without a backtrace is not really useful.
Thanks for the quick response. I suspected that the problem was independent of the collection size. Here is the backtrace: Application: Amarok (amarok), signal: Segmentation fault [Current thread is 1 (Thread 0x7f01bc549780 (LWP 3482))] Thread 14 (Thread 0x7f01a4dd2710 (LWP 3483)): #0 0x00007f01b784cbc9 in pthread_cond_timedwait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 #1 0x00007f01aaad2081 in ??
