Therefor the dialog should be simple to understand without reading a lot of
text, preferable reading only the buttons. The latter is not impossible if all
the questions for kde are in like manner so if someone understands the common
line in the requesters he/she could predict the question asked.

The text should be read, but complicated questions are not easy to answer, when the user is in a hurry. So that´s why the buttons should represent a SPECIFIC answer to the question. (Yes/No is obviously NON SPECIFIC !)

Print file?
[Ok] [Cancel]

Why that?
Should´nt it be [Print] and [Cancel] ?
Clicking is "the action", so "the user prints" when "s/he clicks"

Read error:
[retry] [ignore] [cancel]

Good!

Shure to remove dir X and everything it contains?
[OK] [Cancel]

[Remove] [Cancel]
could also be [Remove file]
This [OK] does give you no information about the question. "OK" is definitly positve, but a rather negative action is going to happen. So this is completely misleading!
I don´t want to say that users are incapable to understand what they read, but again - when things have to be done quickly, decisions are not done by brainwork, but by intuition. And so intuition is what has to be the guide for button-design!
