well well... I had the exact same problem. when I removed kaffe, it gave me this:
Preparing to install...
Extracting the installation resources from the installer archive...
Configuring the installer for this system's environment...

Launching installer...

/usr/bin/java: /usr/bin/kaffe: No such file or directory
/usr/bin/java: exec: /usr/bin/kaffe: cannot execute: No such file or directory

???? I am sooooo confused....
