Description of problem:
Starting it from the menu yields:
1. A blank terminal
2. A dialog:
[ Close ]
3. Accepting the dialog adds 'Press ENTER to exit' to the terminal.
Version-Release number of selected component (if applicable):
Meanwhile run it as root (/usr/sbin/chkrootkit).
The desktop menu uses consolehelper/PAM, and it sounds as if there
have been changes which break something.
Fix is building as: chkrootkit-0.47-7.fc7
The poor "Unknown error." dialog is what happens in consolehelper-gtk
under certain circumstances.
