query raster/vector map(s) does not work with vector layers

[pvanbosgeo]

The query raster/vector map(s) function does not work with vector layers. Clicking anywhere on the vector layer returns nothing except the following in the command console:

Duplicate of #2431

I had seen the bug report #2431, but wasn't sure it was the same as that bug report mentions problems when there are multiple cats per mapping unit? In my case it happens in layers with only one cat per mapping unit.

Replying to pvanbosgeo:

I had seen the bug report #2431, but wasn't sure it was the same as that bug report mentions problems when there are multiple cats per mapping unit? In my case it happens in layers with only one cat per mapping unit.

The bug seems to be a result of the fix for #2431. ​https://trac.osgeo.org/grass/ticket/2431#comment:6.
