Homebrew, Mac 10.9, and Pango: Fontforge crashes on start

I am running OS X 10.9, Xcode 5.0.1, XQuartz 2.7.4 and Homebrew.

Homebrew prefix is freshly installed.

The following command was used to build with Homebrew:

    brew -v install fontforge --with-cairo --with-czmq --with-gif --with-x --with-libspiro --with-pango



When I build fontforge with Pango support, fontforgs crashes at start, as follows:

    ~> fontforge

Everything works fine if I build without Pango

    brew -v install fontforge --with-cairo --with-czmq --with-gif --with-x --with-libspiro
