Quartus II and Ubuntu 7.04?

I'm trying to install Quartus II (7.1) on Ubuntu 7.04, but when I try to run the GUI (in altera7.1/quartus/bin/quartus), it seg faults without giving any meaningful error messages.

Has anyone else experience this, and perhaps found a solution?

The same version of Quartus II ran on Ubuntu 6.06 and 6.10 (with some minor problems if you went into certain menus).
