Solution
Please Install the Updated Packages.
Insight
The kdewebdev4 package shipped in Mandriva Linux 2009.0 contained several packaging bugs. One is that kfilereplace and kxsldbg had file conflicts on icons, and the other was that no meta package called 'kdewebdev4' was provided. The latter issue would cause kdewebdev4-devel to be installed when asking to install kdewebdev4.
The updated packages fix these packaging bugs.
