Steps to reproduce on Windows:
1. Go to about:config and middlemouse.paste to true.
2. Copy something to the Windows clipboard.
3. Load the testcase.
Result: the contents of your clipboard are pasted once a second.
On Linux, I imagine this would paste the X primary selection rather than the
contents of the clipboard (without any hidden pref changes).

Lest people discount this bug due to the first step being "change prefs", Unix
and OS2 versions ship with true already the default value.

a=asa for aviary checkin pending reviews.
Fixed on 1.7 and trunk too (a=asa over IRC).
on linux (2004102409-0.9+) this seems to behave itself now.
