hi,
i have many little survey with local coordinate, this can correctly georeferenced with USER CRS, but when the CRS is writed to PRJ file (with same name and same directory of DXF and PDF) Qgis cannot automatically read the correct USER CRS. When DXF is converted to SHP (with PRJ file) Qgis open them correctly.
Many Thanks

sample USER CRS:
+proj=omerc +lat_0=46.2 +lonc=11.2 +alpha=22 +k=0.2 +x_0=-2000 +y_0=-1000 +gamma=0 +ellps=WGS84 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs

sample USER CRS writed PRJ file:
PROJCS["Hotine_Oblique_Mercator_Azimuth_Center",GEOGCS["GCS_WGS_1984",DATUM["D_unknown",SPHEROID["WGS84",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Hotine_Oblique_Mercator_Azimuth_Center"],PARAMETER["latitude_of_center",46.2],PARAMETER["longitude_of_center",11.2],PARAMETER["azimuth",22],PARAMETER["scale_factor",0.2],PARAMETER["false_easting",-2000],PARAMETER["false_northing",-1000],UNIT["Meter",1]]

just had a chat with others here at the developer meeting and, as I supposed, is wrong to assume that you can simply add a prj file to file formats that do not make use of prj files, like dxf and pdf.
