I use it in browser mode, with Artist/Album panes on the left and Title/Time on the right.
System is Ubuntu 12.04 up-to-date.

Noise crashed after only 20 seconds playing an mp3...

[Corentin Noël (tintou)]

Is this still happening ?

[Expired for Noise because there has been no activity for 60 days.]

[xapantu (xapantu)]

So, after some investigation:
it looks like it is related to a thread problem.
it is in the last.fm plugin, it seems that commenting lines 84-85 of SimilarMedia.vala:
similar_playlist.add_medias (Noise.libraries_manager.local_library.medias_from_ids (similarIDs));
similar_retrieved (similarIDs, similarDont);
solve the problem (but of course it breaks the plugin).

It easily reproducible if near all the RAM/CPU is used.

Let me know if anyone meets this bug again, it is hard to reproduce, but it should be fixed (it will be in the daily ppa in a few hours).

[Li Chong (l-chong-v)]

Seems it works. Congrats
