This one is a gray area however based on my understanding of the
following:
The rendering engine/etc used by KDE Pim didn't support JavaScript
Things changed and JavaScript support was introduced
The devels realize this, and quickly move to disable JavaScript.
It seems like JavaScript was never meant to be supported in KDE Pim,
so in light of that I'm going to assign this a CVE as JavaScript
introduces a significant number of security issues and also violated
the principle of least surprise.
Please use CVE-2012-3413 for this issue.
