I cannot reproduce the error.
There have been post about similar errors, for example
this one.
Which version of wxWidgets2.8 do you have installed ?
And which suite of the deb-packages ? testing or unstable ?
I use unstable on my system, it's exactly the same build then the one in repo.
The packages are build with pbuilder. to make sure there are no broken dependencies, because on my working-system there are also some libraries from experimental .
Nevertheless I updated the repo to svn4547, but this should not make a difference.
