Version: 0.12.3 (using KDE 3.5.5, Debian Package 4:3.5.5a.dfsg.1-6 (4.0)) Compiler: Target: i486-linux-gnu OS: Linux (i686) release 2.6.18-4-686 When a font is set in an msn conversation, it stays set for protocols that don't offer font changing (ICQ), so at first, user stays confused how should he change the font back, and th e procedure to change it is to start some msn conversation, change the font back to normal, and then continue with the ICQ conversation.
In kopete svn trunk r835161, the font settings dont even stay for msn ( see bug http://bugs.kde.org/show_bug.cgi?id=147691 ) so maybe not fixed but at last this bug isnt valid anymore for the newer kopete versions ;)
I tested this too with kopete from KDE 4.0.99. Even if I set a wierd font in msn, font in icq doesn't change (and I changed font in msn being careful enough not to hit bug 147691). So this bug doesn't exist anymore.
