debian kde will not install deb from dolphin by default

[Fabio Rafael da Rosa]

Hi all.
I'm asking here before writting a a bug report, to check if it is 'by 
design', and, if it is, why.
I just made a fresh wheezy install and choose kde as the desktop 
environment from the installer.
After the first boot, I did download google-chrome from the website, and 
tried to install it, without success.
I did test this, because I'll make this install to a friend, to replace 
his Window XP.
I did check that, for being able to install something from the UI, with 
a double click, I must install gdebi-kde.
Why is that not installed by default ?

Thanks in advance.
Regards
