[Proj] Winkel Tripel Problems

Hi all,

since I'm working with QGIS (which relies on proj) I wonder why Winkel
Tripel is not supported. I understand that Winkel Tripel is integrated
in proj (+proj=wintri) but that seems not to work. For Example, defining
a user projection with +proj=wintri within qgis and then trying to
project (on the fly) a dataset of epsg:4326 (plate carree) to this
projection fails. Instead qgis shows the existing dataset in epsg:4326.

Anyone out there with a solution?

Thanks in advance, Lars
