Kmail2 - Configure Special Window Setting: does not register (sid)

[inkbottle <inkbottle007@gmail.com>]

Since I was upset with Kmail always opening in fullscreen, I decided to let go 
of fixing things, and instead force it to do what I want through `Alt f3` 
"configure special window settings".

So I just do that, and click OK, in the dialog, and then the screen flashes as 
it usually do in that specific situation, and then the "settings" window is 
gone, just as it does nowadays, and then I go in "settings" and "windows 
rules", in order to set the specific parameters I want it to assume, and then:

dah-dah! Nothing. Nothing it registered at the name "Kmail", or "Kmail2" as 
the dialog called it.

I already have four of them, three of them long standing, and one newly 
created, for firefox, which was stubbornly opening in very small window, and 
that I had to tame (as a matter of fact it started behaving like a bad 
application a few week ago too).
Anyway, I usually know how it works.

The long standing are emacs konsole and okular and are of the "application" 
persuasion.

The new one is of "window settings" sort.

Anyway, following these directions, it doesn't work, doesn't do anything; but 
it duly flashes the screen, showing it did do some real work in the configure 
window setting line.

Weird.

I tell you if I have more data.

PS: I did `rm -rf ~/.kde4`, in order to remove all easy and safe to remove 
settings and config things, as I've been recently suggested to do, some times 
before the above thing.
