We have an agent (UIElement) process, using GC, that can open a custom document
type. Other than it being an agent, there’s nothing particularly special going
on.
On Lion, when one of these documents are opened, the window appears, but then
the application promptly has an uncaught exception and crashes. The difficult
matter here is that there’s no code of ours in the stack trace involving the
exception, it just looks like internal NSDocumentController machinery, and
everything works fine on 10.6. So while as a first pass this looks like it
could be a Lion bug, I thought I’d run it past the hive mind here to see if
anybody has seen any issues like it themselves and have any insight into a
workaround or anything that we could be doing wrong to be causing it.
