Description

When loading a wms (eg http://geodata.nationaalgeoregister.nl/ahn25m/ows and then select layer 'bladindex'), loading is ok.

Then select the i-tool and click in the map.

First time it shows ok (with Format=Html), Text is also ok, but as soon as you choose format 'feature' qgis crashes.

running at in debug mode:
