	File "proxy icon" in NS title bar on OS X is not reliably shown
Date: Wed, 13 Apr 2011 14:02:51 +0100

On OS X, try opening a file in a GUI frame:

  /Applications/Emacs.app/Contents/MacOS/Emacs -Q ~/.bashrc

There will be a proxy icon for the file in the Emacs frame's title bar.

Now eval the following expression:

   (setq frame-title-format '("%b"))

The proxy icon will disappear. It can be made to reappear by setting
frame-title-format back to t, and at times the icon has then remained visible
even when re-setting a custom value for frame-title-format.

I'd expect that the icon would always be shown when the current buffer
has an associated file, and the current behaviour appears incorrect.

Please let me know if I can help by providing further info.

Just wanted to note that this bug is still present in Emacs HEAD as of yesterday. It's very convenient to be able to drag the file icon to other applications, so I miss it when it's mysteriously not there.
