You probably face gdb bug #56391. The crash report you attached previously had a backtrace, do you still get one after the crash? It should have a debug backtrace if you have rhythmbox-dbg installed
-- crash after drag and drop of songs to the rhythmbox window in edgy https://launchpad.net/bugs/61936 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
