Ah, the horror, the horror!
Apple says downgrade the quicktime version; you really should upgrade limewire too. All should be good then. The newer versions are so much better and have automatic bug reporting, which is easier than emailing the text to bugs@limewire.com

for the quicktime, see http://www.info.apple.com/kbnum/n93414

Cheers. Conrad, I presume?
