One of those applications is "kde"!  I don't know if the problems are
originated from gcc4 issues of from kde issues.  Problem is that
the compatibility version "gcc32" could be good for most of kde, but
not for the whole of it; as an example I already pointed out the
case of "kig" which compiles with gcc32 only with python-scripting
disabled due to an incompatibility of gcc32 with the boost libraries,
while it compiles fine with gcc-3.4.2.

As a result FC4T3 has kig with python-scripting disabled, which is
a real pity, since in FC3 scripting in kig was perfectly functional!

I opened a bug with bugzilla related to this issue a few days ago, 
but I did not get any feedback yet.
