Description of problem: This is a packaging issue. You recently released libstdc++-3.4.4-2.fc3, but the most recent release of gcc4-c++ requires libstdc++ = 3.4.3, and should be updated as well. Version-Release number of selected component (if applicable): 4.0.0-0.41.fc3
And the problem is? libstdc++-3.4.4-2.fc3 provides libstdc++ = 3.4.3 as well.
The problem is that I didn't look into this very well before I reported the bug. It is apt which doesn't understand libstdc++-3.4.4-2.fc3's provision of libstdc++ = 3.4.3. Sorry.
