 When trying to pass a block as the completion handler for
 beginSheetModalForWindow, my application crashes. Machines installed with
 BridgeSupport preview 3 work just fine, and passing the --bs flag to embed
 all bridgesupport files does not resolve.

 Crash report indicates EXE_BAD_ACCES.

 On a side note, is there any way to test distribution for computers
 without latest BridgeSupport? Currently I have to send a build out to a
 user and have them check console and crash reports to debug what's going
 on. It would be nice to be able to somehow do that locally, or at least be
 able to revert BridgeSupport version when testing.

 Code:

 {{{
 def browse(sender)
     dialog = NSOpenPanel.openPanel
     dialog.canChooseFiles = false
     dialog.canChooseDirectories = true
     dialog.allowsMultipleSelection = false
     dialog.canCreateDirectories = true

     dialog.beginSheetModalForWindow(
       sender.window,
       completionHandler:Proc.new { |pressed|
         if (pressed == NSOKButton)
           puts "YAY!"
         end
       }
     )
   end
 }}}
