segmentation fault

[Khusnutdinov Nail]

Dear colleagues, 
I just installed lyx 1.5.4 by using repository of Fedora. My system: 
ASPLinux 12 (based on Fedora 7). I use KDE 3.5 but with installed parts
of KDE4 and Qt4. When I start in console lyx I obtain result:
"segmentation fault" and the program does not start. What is the
problem? I did not find discussion of this question in internet.
