Hi,
Anybody know anything about NSDocumentTitlebarPopoverViewController, and/or why I’m getting application crashes due to a zombie’d instance thereof?
Document-based app, Deployment Target and SDK both 10.8. Built using Xcode 5.1.1 (5B1008) on Yosemite 10.10.3; running on the same system. Here’s what I do:
1. Run my app.
2. Open an existing document from disk.
3. Click on the document name in the window’s titlebar to open the Document name/tag/location popover.
4. Wait a second or two.
5. Click elsewhere in my document window to close the popover.
6. Crash.
Sometimes the crash happens immediately after the popover disappears; other times it happens 1-3 seconds later. It doesn’t happen every time, but always within two to three repetitions of steps 3–5. Here’s the stack trace when it crashes:

After enabling Zombie Objects, I get the following in the console:
2015-05-28 14:19:58.291 MyApp[23684:2561441] *** -[NSDocumentTitlebarPopoverViewController isKindOfClass:]: message sent to deallocated instance 0x600000146f60
Google is no help, although it did uncover the following tweet from just a few days ago: https://twitter.com/tonyarnold/status/603424801152086017.
Anybody run across this before, or have any thoughts on what the problem could be and/or how to debug?
Thanks!
Matt
