|Crashes QGIS or corrupts data:||Copied to github as #:||12847|
When I import a Raster to QGIS through GRASS, with Value Tool Plugin Activated, it gives the following error message
An error has occured while executing Python code:
Traceback (most recent call last):
File "/home/alt-shn/.qgis/python/plugins/valuetool/valuewidget.py", line 134, in printValue
AttributeError: 'NoneType' object has no attribute 'minimumValue'
2.6.4 (r264:75706, Dec 7 2009, 19:02:09)
Furthermore, the error message repeats itself everytime I click on the "close" Button and I have no choice but to shut down and restart QGIS

this is unfortunately a known problem. The GRASS raster provider has changed and fixed a few nasty bugs, but had broken a few other things, among them there is the value tool plugin. In any case the plugin is a 3rd party one, so its bugs nust be reported directly to the author and/or to the dev mailing list.

BTW it doesn't crash. valuetool should ignore grass raster layers (at least for now). the error message only appears when you move the mouse pointer inside the map canvas, so you can move it outside, close the error message using the keyboard and disable valuetool in the plugin manager.

Looks like the current version already does. I made a patch that adds support for grass rasters: http://lists.osgeo.org/pipermail/qgis-user/2010-June/008872.html
