[Chameleon] Can't find bug listed?

[Jonathon Coombes]

Hi,

My Javascript console is reporting repeated errors about captureEvents 
() being deprecated and lists bug #330494 as the culprit. However, on  
searching the bug list at the Chameleon site, there is no listed  
330494 bug, nor can I seem to match any bug to the search for  
captureEvents? Where can I find information about this bug? Does it  
really exist?

Regards
Jonathon
