also look in &/or clear out files in ~/grassdata/wms_download/.
For me the instead of a PNG image the file actually contains
WMS XML capabilities with little indication of what was wrong
that I could see. for debug you get a .wget file in the
wms_download/ cache directory with the tile's raw download
command.

it's quite frustrating to support WMS, every WMS server likes
to respond to query failures in its own different and unique
way.

fwiw in qgis 1.8.0 I could get that server to return data, but
something wasn't quite right with the positioning.

I believe the grass 7 version lets you try a number of different
methods? maybe more luck with something other than the default.
