[Bug 28578] Editing a wiki page strips out carriage returns from all preformatted text on that page

Chrome, Chromium, Opera, and Konqueror all give me the same non-GUI display in
the GUI editor as in the screenshot, and the buttons don't work (except for
cancel).

The GUI editor mostly works in Firefox and SeaMonkey, except for the problem of
stripping out carriage returns in preformatted text when I save, and as I've
now discovered, dropping tables. The tables at the bottom of the wiki sandbox
page don't display in the GUI editor--I'll post a screenshot of that.

I tested this on two distros (openSUSE and Linux Mint), installed on different
machines.

Since the two of you can't reproduce this: is there something (library,
extension) you can think of that a developer would normally have installed on
their system (and take for granted) that a non-developer might not?
