Konsole white background, tabs on bottom. Resolved. The original 3.5.10 kdebase Slackware build script created a file in /usr/share/config named konsolerc. That file specified the default schema as Linux.schema. Adding that snippet to the Trinity build script seems have solved the problem. My testing version of Debian Lenny does not have a /usr/share/config directory. I'm guessing then Lenny inherits the defaults of the upstream KDE. As Lenny exhibits this white background, tabs on bottom behavior, I'm guessing the original default 3.5.x konsole must use the BlackOnWhite schema. Trinity inherited these same defaults, hence the same behavior.
