Comment 1 for bug 1102672

Oh, as for the result of an attempted connection:

The QTNX dialogue box remains on-screen, there is no remote-X window appearing, CPU usage on my PPC laptop sits at 100%, and no errors/warnings/witticisms are displayed in the terminal window.

Here is a log-snippet from the server-side:
