[Sparkle] Sparkle causes crash on launch with custom URL, RubyCocoa

[Andy Matuschak]

Okay, I think this is happening because some value's being saved or  
interpreted as an NSString instead of an NSNumber, and I'm calling  
longValue expecting the latter. I've changed those calls to  
doubleValue, which is implemented by both classes. Update to bzr  
revision 124 and give it another shot.
