[Eric] any problems after qt 4.5.3 upgrade

[Linos]

Hello,
	i am using eric 4.3.8 but i have the same problem if i downgrade to 4.3.7, 
after the upgrade from qt 4.5.2 to qt 4.5.3 the keyboard it is not working 
inside eric, i have no problems with others qt or pyqt applications, but in eric 
i have this problems:

	-the shortcuts don't are created correctly, for example inside "Start" menu 
"Run Script" and "Run Project" uses the same "F2", "Run Project" not get his 
SHIFT modifier and the same happens with "Debug Project".
	-inside the code editor i can't use the arrows or the backspace, but space and 
letters works.
	-the problem about the cursors it is in other less visible ways too because if 
i use "ctrl+f" inside the code editor i get this:
		Warning:
		QAction::eventFilter: Ambiguous shortcut overload: Ctrl+F

I have tried all i can think of to fix it, i have updated sip, pyqt and 
qscintilla to the lastest snapshots, i have compiled qt without the kde patches 
my Arch distribution add to the package, all without luck, i dont know why it is 
happening, but if i downgrade to qt 4.5.2 (that i am using because of this 
problem to can use eric) all works well, any clues about this problem please?

Regards,
Miguel Angel.
