Many thanks for making RPMs. If it's of any use, I would like to share errors I'm getting:

on my PowerPc Fedora 10 install, launching Songbird yields no result. Nothing happens. I imagine the ppc build is of the least significance to the least number of users, so more importantly-

on my pc laptop x86_64 install, I get above javascript error at launch. i hit ok. then, upon attempting to play any tune, i get nothing ie, "nothing playing" in display. if i restart, sometimes it will show me what should be playing- but it will stay at 0 seconds. A couple of times I got a media core error:
"internal data flow error."

but that hasn't happened in recent restarts.

Since installing I have not been able to play a single song.

I have tried out the latest songbird, outside of linux, and think it's fantastic. Your efforts are greatly appreciated- I think once it's running smoothly Songbird will be best open source media player, more versatile even than closed iTunes and that some distro would do well to make it their default player. I look forward to running it in Fedora and will check back for updates. Thanks again.
