Doubleclick interval not set for non kde apps

I reported this as 'bug 294443' on kde.org, but I'm resubmittiing here because it's a ubuntu specific bug:

Kubuntu 11.10 KDE 4.80 If I set mouse click interval to 800ms in system
settings, KDE apps set correctly, but non-KDE apps click interval remains at
default 200ms.

If I Boot same system into Gnome or Unity all apps work perfectly -- no
interval problems.

I installed KDE on Fedora 16 and problem goes away as with Gentoo and
Slackware.

This only occurs on ubuntu's port of kde and is started back when KDE 3x went
to 4x

Reproducible: Always

Steps to Reproduce:
Just install kubuntu, run system settings, and set mouse double click interval
to 800ms.

Actual Results:
KDE apps have a correct interval of 800ms as configured, but non KDE apps
remain at the default 200ms interval.

Expected Results:
KDE apps have a correct interval of 800ms as configured, and non KDE apps also
change the default 200ms interval to 800ms.

I have a disability that prevents me from double clicking under 700ms.

I reported this bug a long time ago 'Bug 268399 - double click select text not
working', but I did not articulate the problem.

Kubuntu has a bug (easily repeatable): mouse settings change mouse double click
interval correctly, but the interval for non-KDE apps (firefox, chrome,etc)
stays at about 200 ms. This bug has persisted through different versions
probably because most people don't notice. I asked my wife to try to double
click select text in Chrome on Kubuntu 11.10 and it works without fail -- I
can't, but on Kate or other KDE apps I can.

As a workaround I installed mousetweaks and wrote a bash script:

#!/bin/bash
/usr/bin/mousetweaks --dwell --dwell-time=1.2 -t 20 --ssc --ssc-time 1.2

This preforms a double click at 200ms.
