I was able to reproduce and fix this problem that went away a few weeks ago. The mystery factor was that the crash only occurs if user clicks on the old (right-screen side) version while in the Versions Browser, which causes its window to resize, before restoring.

Apparently, objc_msgSend_vtable5 implies -respondsToSelector: > Odds are that this is a message being sent to [self delegate], which looks > like a deallocated object. Indeed, that is what was happening. I was sending setDelegate:nil during -windowWillClose:, but the message was not being delivered because when I replaced RBSplitView with NSSplitView to make the project buildable in Xcode 4, I neglected to reconnect the outlet from the window controller to the new NSSplitView. It's connected now, and no more crashes. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
