I tried running Banshee with --debug parameter (to get some more information), but with that everything went fine, all songs were imported without crashing. I hope this helps too...

P.S. After importing all the songs (44000+), database search is a bit slow. After clicking on an artist name, I have to wait 5-20 seconds before songs from that artist are displayed. I know it can be faster, gmpc, for example, on the same machine gives instant results.

In my previous test, I didn't know that scanning continued from where it was stopped in previous crash. After deleting the database (the whole .config/banshee-1/ directory), crash occured even with --debug. My first two testings were done with Banshee version from maverick-updates/universe.

I did more testing with Banshee 1.8.0 from stable PPA, and also with unstable (1.9.0) PPA. The results are the following:

After running 1.8.0 from stable PPA, importing with or without --debug gives this error after a while (with --debug, it scans more songs than without before crash):

1.9.0 with --debug freezes often during scanning (it's window just turnes grey and rescanning indicator stops), currently is at 8% without crashing, but I cannot forsee how long it would take. When it finishes, I will post the result.

Testing 1.9.0 from unstable PPA with --debug parameter (database erased before testing):

I left home for 5 hours, and after that the percentage of imported songs jumped to 17% (around 9000 songs imported), but so far, no crashes. The program very often waits for this (debug output), without importing anything:

-----------------------------------------------------------

I selected "Disable features requiring internet access", restarted program (it froze), and after that continued to import songs (now without pauses - it finished in a few minutes). Also, no crashes.

I don't know why importing crashes when started without --debug, and works with it. After importing, I didn't notice any bugs so far, and the searching speed wint SQLite 3.7.3 (added from debian/sid) is excellent - almost instant results.

Alexander,
I'm sorry, but I was using precompiled Banshee from Banshee Team's PPA, first stable (https://launchpad.net/~banshee-team/+archive/ppa), then unstable (https://launchpad.net/~banshee-team/+archive/banshee-unstable) and, as I can see, I cannot apply patch to it. I didn't import anything new last few weeks, but as I can see, unstable version is now 1.9.2, and I will test it again (deleting the database and importing from beginning).

Zarko, ping, any update for the bug ?

Sorry about lack of reports. I have been occuppied with other things (I'm using Banshee, but I wasn't importing files for some time), but thanks for reminding me. I tested importing files in the latest unstable version from ppa (1.9.5). After removing the database, I started banshee and started to import all music files. At the beginning, the adding was fast, but after 200-300 songs it would stop for a ~20 seconds, while boosting CPU usage to 100% (this might be beacuse I didn't disable internet access at the begining; I remembered to do this after a couple of minutes). Anyway, during import I had only one crash:

After starting banshee again, the rest of the files (something over 50000) were imported without crashes (and reasonably fast, too). That is excellent! Thanks for all the work you guys are putting into Banshee.
