Invalid sample dimension with some WMS servers

[goyodiaz]

Connect to this WMS server: ​http://www.idee.es/wms/MTN-Raster/MTN-Raster? and add the only layer to the project. This warnong is displayed:

Request contains an invalid sample dimension value. The WMS vendor also reported:

This is because the image with the thumbnail for the legend can't be served. Everything else works but the message is annoying and appears every time you open a proyect with this layer (several times if you have several layers with this problem in the project).

Reproducible in Ubuntu and Windows using trunk.

In QGIS 1.7 you'll be able to select the size of the tile to use when adding WMS layers. I just tested trunl with your WMS server and it works fine (no error message) choosing -for example- a 256x256 tiles size.

Sorry if I'm just making noise but I still get a warning using 256x256 tiles. I'm attaching a sample project which causes the problem on opening even using 256x256 px tiles. The message is just a bit different:

This can be avoided by unchecking "Create raster icons in legend" in general options, which is convenient for me, so I'm leaving the ticket as closed.

probably my bad. Setting tile size at 512x512 no problems.
