The parameter representing a connection to the window server is invalid.

It looks like the Cocoa aspects of your application don't have a proper connection to the window server. NSImage uses the window server to create a target graphic context when you attempt to draw into it.

Have you tried adding in a call to [NSApplication sharedApplication] someplace in your application initialization? This kicks AppKit to bootstrap itself.
