[Adium-devl] Odd new WebKit leak in 1.0.4b4 - WebImageData

[Evan Schoenberg]

Opening and then closing a message view in 1.0.4b4 permanently adds  
to memory. WIth the aid of OmniObjectMeter, it's clear that the vast  
majority of the WebView heirarchy is indeed being released.  However,  
a WebImageData, WebImageRenderer, and WebTextRenderer get leaked  
somehow alongisde each view... note that we never touch these three  
classes directly.

WebImageData is a particularly problematic leak, because it allocs   
(and, when deallocated, will free) significant chunks of memory for  
displayed images.  WebImageRenderer creates and retains it, so that  
sticking around is the root cause.

Its pathway is:
alloc/init/autorelease by QPixmap::receivedData(QMemArray<char>  
const&, bool, khtml::CachedImageCallback*)		(retain count 1)
retain by QPixmap::receivedData(QMemArray<char> const&, bool,  
khtml::CachedImageCallback*)  					(retain count 2)
release by NSAutoreleasePool																				(retain count 1)

I don't have further time to investigate this one... could someone(s)  
please investigate it and see if it can be squashed?
