Bug#968372: sylpheed: crash on startup

Dear Maintainer,
I could reproduce it inside a i386 VM and found the crash
happens in [1], when it tries to dereference the "state".
This state is retrieved from the renderer of type _PangoRendererPrivate.
I tried to follow where this state is last set and found
this memory is last written in location [2].
But here this memory is used as _GdkPangoRendererPrivate,
which looks quite different.
Kind regards,
Bernhard
