Segmentation fault in version 2.7.2 and 2.7.5b2 on Ubuntu 8.10

Hi,

I wanted to use the BreveIDE on Ubuntu 8.10. First, I downloaded version 2.7.2, but executing breveIDE gives me the message 'Segmentation fault'.
On the forum here, I came across a beta, version 2.7.5b2. Also this version gives the message above.
My system is a Celeron M 1300 MHz. It has OpenGL support (at least "glxinfo|grep rendering" goves 'direct rendering: yes').

Can someone help me with this problem?
