Description Paolo Maggi 2006-04-20 14:58:23 UTC 
Using gedit with gtk+ CVS HEAD I got the following warning:

sys:1: GtkWarning: gtk_text_buffer_serialize: assertion `GTK_IS_TEXT_BUFFER (register_buffer)' failed
sys:1: GtkWarning: gtk_selection_data_set: assertion `length <= 0' failed

Since I never got this warning with gtk+ 2.8, I think it could be a problem in the new gtk_text_buffer_serialize function.
More details will follow if I will be able to reproduce the warning.
Comment 1 Michael Natterer 2006-04-27 10:19:06 UTC 
gtk_text_buffer_serialize() is used only when doing copy & paste
or DND of text. Try playing with these functions when trying
to reproduce the warning.
Comment 2 Paolo Maggi 2006-04-27 16:34:08 UTC 
To reproduce it with testext:

- Run ./testtext
- Open a document
- Select a word
- Press Ctrl+C
- Quit testtext

I have a clipboard manager running.
I only copy without pasting the test.
Comment 3 Michael Natterer 2006-04-28 12:13:45 UTC 
Fixed in CVS:

2006-04-28  Michael Natterer  <mitch@imendio.com>

	* gtk/gtktextbuffer.c (create_clipboard_contents_buffer): keep a
	reference to the source buffer while the clipboard contents buffer
	exists, because it is needed for serializing the contents buffer.
	Makes copying from the contents buffer possible even after the
	resp. text view is destroyed (for example when there is a
	clipboard manager running on app exit) (bug #339195).
