I was having a problem with Kubuntu rendering certain GTK applications with huge, ugly fonts. It was fixed after I read this forum post:

Basically,
apt-get install gtk2-engines-gtk-qt
fixed the problem for me.
I just found a handy utility called PassPack (http://www.passpack.com/info/home/) which is a web application for managing your passwords. It appears to be quite a nice application, but my first concern when I saw it was, of course, security. After googling around for some other opinions on safety, I found this link, http://www.theprivacyguy.com/2007/04/11/passpack-password-manager/, which seems to agree that it is safe.
