Version:           gideon (using KDE KDE 3.0.9)
Installed from:    Debian testing/unstable Packages
Compiler:          gcc version 2.95.4 20011002 (Debian prerelease)

Was unable to Settings->Configure Gideon... after installation.
But after I created a project it was ok.  Traced it to "Last Project"
in General Options. 

.kde/share/config/gideonrc

[General Options]
Last Project=/space/hello/hello.kdevelop
