The following error happens whenever I interact within the Clipper tool (raster/gdal tools):

#1 Updated by Giovanni Manghi over 12 years ago

  • Affected QGIS version set to 1.7.3
  • Crashes QGIS or corrupts data set to No

This does not happens on QGIS-master/osgeo4w

How do I get this error on 1.7.3:

new project

add a raster

raster -> clipper

mask layer -> go pick a vector -> after clicking "ok" the message pops up

  • Status changed from Open to Feedback

Please check on master and give further details.

#3 Updated by Giuseppe Sucameli over 12 years ago

It's due to a python bug, fixed in python v2.5.3 and v2.6.1 (see http://www.riverbankcomputing.com/pipermail/pyqt/2011-February/029218.html).
AFAIK there no way to handle it, except commenting that line...

#4 Updated by Paolo Cavallini over 12 years ago

  • Status changed from Feedback to Closed
  • Resolution set to invalid

This depends from the Windows packaging (old version of Python). Nothing to do with QGIS.

Better helping osgeo to upgrade their Python, long overdue.
