crash zooming to a raster not matching the project's projection

[tutey@…]

QGIS SVN 6248:

1. added few shapefiles of unknown projection

2. set the projection to EPSG:4179, enabled on the fly

3. added a raster of a different projection, namely:

Driver: GTiff/GeoTIFF
Size is 3800, 2500
Coordinate System is:
PROJCS["TNTmips Georeference",
    GEOGCS["WGS 84",
        DATUM["WGS_1984",
            SPHEROID["WGS 84",6378137,298.2572235629972,
                AUTHORITY["EPSG","7030"]],
            AUTHORITY["EPSG","6326"]],
        PRIMEM["Greenwich",0],
        UNIT["degree",0.0174532925199433],
        AUTHORITY["EPSG","4326"]],
    PROJECTION["Transverse_Mercator"],
    PARAMETER["latitude_of_origin",0],
    PARAMETER["central_meridian",15],
    PARAMETER["scale_factor",1],
    PARAMETER["false_easting",3500000],
    PARAMETER["false_northing",0],
    UNIT["metre",1,
        AUTHORITY["EPSG","9001"]]]

4. zoom to raster -> crash; the bt:

I know the projection I declared and raster's projection don't match, but this I learned in the process and QGIS shouldn't crash in the first place.

[homann]

Is it possible to attach raster and/or the dataset?

[tutey@…]

Replying to homann:

Is it possible to attach raster and/or the dataset?

Sorry I don't have it anymore. And I can't reproduce with other dataset at will. The procedure in general should be:

1. add a shapfile without *.prj

2. set some projection, enable on the fly

3. add a GeoTIFF with a projection different than set in step 2.

4. zoom to raster -> crash

Maciek

[gsherman]

this can be duplicated by loading any shapefile with a projection different from the raster, setting the projection to a third projection, then adding the raster.

Zoom to raster causes crash.

[anonymous]

Partial fix in svn r6341. Qgis shouldn't crash now, but it doesn't quite yet zoom to layer extent correctly for all combinations. Note that the zoom to layer extent button in the toolbar does work correctly - the zoom to layer in the legend is the problem

[g_j_m]

Fixed in svn r6345. No longer crashes. Better behaviour when projecting between incompatible coordinate systems could be an enhancement for later versions of qgis.
