Well, can you provide a full error or does it only give you a segmentation fault?
Where did you install it to? How did you install, by source or RPM? What do your current log files look like if you've tried to see if it provides any more information? When you installed, were there any error of any such?
Have you tried searching on "segmentation fault's" ?? There are tons of information regarding them online, on this site.. etc!
