Please install debugging symbols for the phonon-backend-gstreamer, this is not a problem with Amarok, but with that backend. Created attachment 80566 [details]
The whole backtrace
Yes. I know the crash problem is more likely a upstream problem and I will file bug report to them once I find more info. (I don't want to file something like "crash unknown reason"). I suspect the problem may be related to crossfade, because play the unplayable file is fine. But the first one, "Unplayable file enter the playlist (using Files media source)", may be a bug of amarok. (That's why I choose the bug component to "File Browser") I find that the "Files" media source can ignore 0 size file, but not anything else. For my case, I have some ._xxx.m4a created by another Apple computer. (My collection is on a NFS and shard by my Linux and my wife's Apple. The apple will create these ._abc.mp3 for each abc.mp3) When I use "replace the playlist" of "Files", it adds these unplayable ._xxx.m4a into my playlist. Which makes my list not very usable. (Playback will stop on these unplayable files even upstream fix the crash problem) Thus, I hope the amarok can fix this by implementing a general filter to exclude files based on regex, or just filtering files starting with ._, as I have mentioned. PS: additional info on the "Steps to Reproduce": The created ._XX.mp3 must have non-zero size. I also fine some additional info on the terminal: (amarok:14322): GLib-GObject-CRITICAL **: g_object_get: assertion `G_IS_OBJECT (object)' failed KCrash: Application 'amarok' crashing... KCrash: Attempting to start /usr/lib64/kde4/libexec/drkonqi from kdeinit sock_file=/home/wujun/.kde4/socket-g/kdeinit4__0 I also reproduce a backtrace with missing symbol fixed.
