That you can't link a GPL program against a library contain such code.
If it is to write an application for Gnome (even part of Gnome) but not
having a library that use said code for the Gnome platform, it is not a
problem. And the Apache License 2.0 is not incompatible with LGPL, which
mean that it can link against Gnome libraries.

And as stated earlier, GPLv3 should address the problem.
