GDALTools: DEM throws an error

[pcav]

When activating the Raster>DEM menu, I immediately get an error:

Traceback (most recent call last):
  File "/usr/share/qgis/python/plugins/GdalTools/GdalTools.py", line 322, in doDEM
    d = DEM( self.iface )

Versione di QGIS:
1.7.0-Wroclaw Wroclaw, 15577M

This with gdal 1.7.3:

>>> from osgeo import gdal
>>> print gdal.VersionInfo("RELEASE_NAME")
1.7.3

Does DEM tool only throw this error? Could you check the gdal version from GdalTools about dialog?

Yes, only DEM. The GDAL version reported in the About is the same as above (1.7.3). Thanks.

I do not understand why, but now it works.
