#19 VDKBuilder error messages

[Ravi]

I installed the latest VDKbuilder in Kubuntu from Software Center. I get the error message when I start vdkb2 from terminal mode:

How can this be fixed ?

I also get an error message the "Widgets are disabled" when the form is loaded.

ravi@ravi-desktop:~$ vdkb2
