KDE freezes after switching to text terminal and back to KDE

["Marcelo Magno T. Sales" <mmtsales gmail com>]

People,

In F10, if I log in to KDE, switch to a text console (CTRL+ALT+F2) and 
then back to KDE, the system switches to graphic mode and freezes. The 
screen stays black and the graphical mouse pointer is shown. Sometimes 
the pointer freezes too, sometimes not. In either case, I have to reset 
the computer. It's not even possible to switch back to a text terminal.
This do not happen if I switch to a text terminal from the gdm login 
screen or from a gnome session. However, the system freezes 100% of the 
times I do this when logged in to KDE.
Any one else has this problem? For which component should I file a bug 
in bugzilla?
