This bug report will be sent to the Bug-GNU-Emacs mailing list and the GNU bug tracker at debbugs.gnu.org. Please check that the From: line contains a valid email address. After a delay of up to one day, you should receive an acknowledgment at that address. Please write in English if possible, as the Emacs maintainers usually do not have translators for other languages. Please describe exactly what actions triggered the bug, and the precise symptoms of the bug. If you can, give a recipe starting from `emacs -Q': 1. Start Emacs.app in OS X (or, presumably, GNUstep). On OS X, $PATH_TO_EMACS_APP/Contents/MacOS/Emacs -Q is fine. 2. Load something in the pasteboard that lacks a plain text representation*. 3. Yank. Emacs aborts the yank with the quit message "empty or unsupported pasteboard type". From my perspective at least, this behavior is never useful, frequently annoying, and particularly painful when `save-interprogram-paste-before-kill' is enabled. My preferred solution is for Emacs to simply ignore unsupported pasteboard data. For example, replacing (defun ns-get-pasteboard () "Returns the value of the pasteboard." (ns-get-selection-internal 'CLIPBOARD)) with (defun ns-get-pasteboard () "Returns the value of the pasteboard, or nil for unsupported formats." (condition-case nil (ns-get-selection-internal 'CLIPBOARD) (quit nil))) has this effect, while retaining the old behavior in the Objective-C implementation for applications that require special handling for empty, unrecognized, and invalid pasteboard data. * Convenient OS X example: without leaving Emacs, take a screenshot with C-Command-# (or whatever keyboard shortcut is defined in System Preferences -> Keyboard -> Keyboard Shortcuts -> Screen Shots for "Copy picture of screen to the..."). If Emacs crashed, and you have the Emacs process in the gdb debugger, please include the output from the following gdb commands: `bt full' and `xbacktrace'. For information about debugging Emacs, please read the file /Applications/Emacs.app/Contents/Resources/etc/DEBUG.
