Thanks for your bugreport. This is most probably an libextractor bug and has been fixed in Basenji 0.9 which introdoced a new metadata extraction backend (taglib-sharp). Unfortunately Basenji 0.9 also introduces the dbus-sharp dependency so 0.8 seems to be the last version supported in your distro :-( As a workaround you can try to disable metadata extraction in the preferences dialog.
