I'm not quite sure what exactly happened, but ever since I instaled rpms for rh7.x of mozilla 0.9.5 my rpm database seems to be broken. Quering package mozilla returns a segmentation fault. Same happens when I try rpm --rebuliddb. I have clean rh7.1 installation with most of the rh updates installed.
CC blizzard who builds the rpm builds (AFAIK)
Umm. There's nothing in the Moz rpms that would do that. It sounds like there's something wrong with your system.
