[Qgis-user] Problem using Grass 7 functions in Processing Toolbox

[mtreg]

Hi All,

I was trying to access some GRASS 7 functions through the Processing toolbox
in QGIS 2.4 (32 bit), but none work (see error message below).  The other
packages I've tied in the Processing toolbox seem to work fine. My machine
is running Win7 64 bit. I've gotten this with versions installed from both
OSGEO4W and the basic QGIS installer.  I've tried suggestions recommended in
this bug report thread with no success: http://hub.qgis.org/issues/10714

Any suggestions or useful interpretations in of the error message?

Thanks!
Mike
