It works for me, I just copy from KFormula, paste in KWord. If there's no
formula frame, it creates one, otherwise it pastes the copied formula.

Using kword 1.6.1 (package from
http://kubuntu.org/announcements/koffice-161.php), I still have the problem.

Launching kword from the konsole, here is an error message :

berti@neptune:~$ kword
kword: ERROR: Missing FORMULA tag in FRAMESET
kword: WARNING: Unknown frameset supplied!
kword: WARNING: KWFrameSet::findAnchor anchor not found (frameset='Formula 1'
frameNum=0)

SVN commit 623001 by abeaumont:

KFormula uses MathML for copy and paste, reflect it in KWord.
