 The query vector/raster map tool on a vector layer does not work. When
 clicking on a layer, the rendering bar in the map display window get's
 stuck somewhere on 50-75%. Moreover, the mouse cursor keeps on spinning
 when hovering over any GRASS window, also after I close the map display
 window (I thought it was related to the rendering of the map).

 I am working on GRASS 7 r54557 (but it started in a previous revision), on
 Ubuntu 12.10, with Python 2.7.3 and wxPython 2.8.12.1. I marked this as a
 major problem as this affects a key functionality i.m.h.o.

 The command line output when trying to query a vector layer is:
