[Qgis-user] No reprojection on the fly for GPX files

Hi!

I've found that QGIS does not apply reprojection on the fly
to GPX files. Is this intentional?
I think that GPX files are always ( by defnition) in lon,lat coordinates and
in 
the WGS84 datum.
I have my gps set for UTM31N ED50, and normally save compegps WPT
files for waypoints (which are saved as WGS84 and lon,lat regardless how the
gps is set).
If I convert that file to shape UTM31N ED50, the file is correctly
positioned
by QGIS (CRS set to UTM31N ED50), but GPX files are always shifted.  I can
save the shapefile
as lon,lat WGS84 and QGIS applies the reprojection on the fly so that the
WayPoints
are well positioned , but the display of GPX file keeps shifted even if I
change the CRS in Properties.

I can provide test files if needed, but perhaps the fact that gpx files are
not reprojected on the fly
is actually intentional.
