[kde] dialog title text doesn't fully show in installer

When installing Kubuntu 9.04 release, most of the progress dialog boxes in the installer are not wide enough to show the dialog title text. The dialog title text is therefore truncated, and practically useless.

It seems that the dialog box only considers the required width of what it contains, and does not consider the title text. Because most of the progress boxes simply contain a progress bar, only 5 or so characters of the dialog title text is shown.

To reproduce - go into the partitioner (don't use the 'entire disk' option), and check out the 'scanning' progress dialog box.

I'm on a machine with a max resolution of 1280 x 800 if it matters.

(Sidenote - it'd be nice if the dialog boxes opened in the center by default, rather than slightly off-center sometimes. And the main installer screen's buttons should be disabled when the system is installing - the modality of the 'installing' dialog is not obvious enough.)
