+1. Sorry Lukáš and Rex, but we should really override the upstream default 
and revert to the Plasma 4 default here.

Automatically locking the screen after n minutes of inactivity is inherently 
flawed and insecure, because it gives an attacker n minutes of time to take 
over your desktop. There is NO alternative to locking your screen manually 
when leaving your desktop. Therefore, supporting automatic locking sends the 
entirely wrong message. (It lets users get away with laziness, until they 
get burned by it.)

And then there is the annoyance factor already mentioned by other posters. 
And the added exceptions for things like video players just make it MORE 
likely that the automatic locking the user was relying on will not happen 
(e.g., because of an embedded video in some web page in the background).

The message should be: If you want the screen to be locked, then lock it. It 
only takes 2 clicks.
