Question to tex_text and svg


I really like the possibility to create labels with tex support. Unfortunately, using this feature, svg export seems to be no longer available. This is sad, because creating svg's was one of my major reasons using matplotlib. Using latex most of the time, it was possible to create high quality vector based images with the possibility to change them later (e.g. with inkscape). I use this feature mostly for language changings of labels or titles.

The error message:

Any idea, how to bring svg export back to work again ?
