I have all the updates installed that are posted on the errata for RH7.

I have installed XFree 4.0.2 and qt-2.2.3

The updates were installed after XFree and qt.  The first time I ran
xf86cfg (new config tool) I got no problems, then the second time it
sigsegv.  I wasn't to concerned at first because it's not very developed. 
Then when konqueror was running it crashed when going to view a web page. 
I've prepared backtraces of both situations, pasted below; the first is
xf86cfg the second konqueror.
