[Gfoss] build virtual raster

[marcozanieri a geosweb.it]

vorrei segnalare un problema nel lancio del comando "build
virtual raster" di qgis 1.4 utilizzando winxp; risulta il
seguente errore:

Traceback (most recent call last):
  File "C:\Documents and
Settings\marco\.qgis\python\plugins\GdalTools\tools\dialogBase.py"
, line 85, in processError
    msg = QString.tr("The process failed to start. Either
the invoked program is missing, or you may have insufficient
permissions to invoke the program.")
AttributeError: type object 'QString' has no attribute 'tr' 

saluti,
marco zanieri
