This does not look like a crash in Amarok at all, at least I see no lines relating to Amarok, might be in vlc, but even that doesn't appear likely
Right, I also wasn't sure where to file this. But given that this is only triggered in Amarok, and not in any other phonon-based application (dragon, juk), I figured Amarok devs would have a better idea of where the issue belongs.
Keep in mind that the Amarok version you use is pre-alpha and yet unreleased. The backtrace mentions vlc once, but apparently the crash is in the underlying system.
Crash is caused by dlopen library loader error, possibly because of a broken ldconfig setup. If this is reproducible with all packages updated from consistent repositories, please report this issue directly to the bug tracker of your distribution.
