Hi,
this is the patch of the other day ported to KDE 4.
It lets us export the Latex formulae as INK Draw gif's, however, it doesn't
work with MSN Plus yet (it seems there is some kind of wrong base64 encoding in
that extension).
Greets.
P.S: I hope this is enough for inclusion.
P.S2: Apply as patch -p0 < patch.txt inside kopete directory (against SVN
revision #681396)
