I've the sema bug, I have a workstation pc with Kubuntu 8.10 and Qt
4.4.3 but a I have a pc with Debian Etch and Qt 4.2.1.

On Debian I can't install Qt Creator so, i develop a simple main windows
with Qt 4.4.3 and when I'll try to compile using "qmake" and "make" this
problem appears. What I do.

Open the .ui files with Kate or any text editor and delete the first
line of this XML file: 

#######################################
<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
.
.
.
</ui>
#######################################

 and let my .ui(xml) file like that:

#######################################
<ui version="4.0">
.
.
.
</ui>
#######################################

so, I delete "<?xml version="1.0" encoding="UTF-8"?>" from my ui and
when I try again to compile in my older Qt version the problem
disappears. I suppose Qt < 4.4 don't recognize the first line of xml and
interpret that like and older qt version.
