So I've been struggling with newer builds of Songbird OSX PPC. It takes a long time to compile XULrunner (the embedded portion of Mozilla/Firefox) and ensure that the library path is not polluted.
The major issue for the XULrunner is that it seems to be blocked from stopping one song and clicking on another to play a new song. Running in to error messages like:
Error: Permission denied to call method Location.toString
which the google suggests is an issue with Flash permissions.
Also running in to spinning rainbow of death for the program attached to a seemingly massive issue with:
_semaphore_wait_signal_trap (in libsystem.B.dylib)
