What other qt4 apps are you running? What's the output of "ldd /usr/bin/skype"?

not sure, sorry.

Comment 3 Russell East 2007-08-27 18:00:51 EDT
After searching, I found this page
in which someone had a (vaguely) similar problem.   In my case it turned out
there were some qt4.3.0 so's in /usr/lib, even though qt4-4.3.1-3.fc7 and
qt4-devel-4.3.1-3.fc7 were installed.   After searching more, I found that I did
not have qt4-x11 installed locally, but some of the 4.3.0 so's were from the
older version of that package.  I can't think of a good reason why those so's
should be there - it's a mystery to me.   My solution was to yum install
qt4-x11, which installed everything up to 4.3.1, and consequently the
incompatibility went away.  I can now run skype once again.
