iphone crashing in iOS 4.2 under "refreshCollections"

[Joseph Heck]

as of rev 93, with the build updated and changed to iOS 4.2 beta, the application crashes on the first refresh of data from the service - under -[OpenStackAccount refreshCollections];

Note: appears to be happening in the +[ASIHTTPRequest initialize] segment - need updated code for iOS 4.2?
