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 -Q'

2. Invoke `M-x rcirc`, go to a channel.

3. Observe: As messages arrive, user nicknames are colored by default.

4. Quit emacs, restart `emacs -Q'

5. In *scratch*, eval `(global-whitespace-mode 1)'

6. Invoke `M-x rcirc`, go to a channel.

7. Observe that when messages come in, user nicknames are not colored.


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'.

The colours in rcirc buffers aren't set by font-locking. white-space
mode re-font-lock the buffer and as such colours are removed. So white
space mode is likely to cause problems in other places.

Shouldn't rcirc use font-lock-face, then?

Not sure. For example, if you turn on whitespace mode in eshell buffer
it also removes the colour there. thus my conclusion g-w-m can cause
problems in other places.

Another way to look at it is that eshell might also need to use
font-lock-face.
