Pasting X selection fails

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,

In GNU Emacs 21.2.1 (i386-debian-linux-gnu, X toolkit)

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Sometimes when I select a piece of text in another program (xterm or tkman
or mozilla are examples, but it seems it can happen with any program) I am
unable to paste the selection into emacs.  Instead, doing the "yank"
command in emacs always pastes emacs' last "kill".  When I do
"Alt-: (x-get-selection-internal 'PRIMARY 'STRING)" the result is also
emacs' last kill, even though I just selected something in xterm a second
before that.

What is interesting is that when I do C-w (killing the yanked kill
again) and then reselect the text in the other X program, it works.

Some environment data that might be useful: 

- emacs is compiled with Athena toolkit
- XFree86 4.1.0
- sawfish 1.0.1.20020116
- no desktop environment

This happens in Emacs 20.7 as well: see
