Lyx problem printing

[Dean Chandler]

I am brand new to lyx/latex/tex.

I installed lyx 1.61  under Ubuntu 8.04, using the Ubuntu backports 
repository. When I tried to print the tutorial, I got the following error:

Lyx: Cannot convert file
An error occurred whilst running python -tt 
'/usr/share/lyx/lyx2lyx/lyx2lyx' -cbig

After this error appeared, the application could not recover, and I had 
to "Force Quit" it.

Thanks in advance!
