[Qgis-developer] WMS provider: Cannot calculate extent

[Casper Børgesen (CABO)]

I have a strange situation. I host two different WMS layers on an internal GeoServer 2.8.2 (type is ImagePyramid) and both layers look fine when previewing them in the GeoServer Layer Preview. I use QGIS Master x64 (latest nightly build from OSGeo4w) to access the layers.
One of them gets added to the map the other one doesn't and give me the following message:

WMS provider: Cannot calculate extent
(..\..\..\..\..\..\src\providers\wms\qgswmsprovider.cpp : 148 : QgsWmsProvider::QgsWmsProvider)
Raster layer: Provider is not valid (provider: wms, URI: contextualWMSLegend=0&crs=EPSG:25832&dpiMode=7&featureCount=10&format=image/png&layers=myns:layer_not_working&styles=&url=http://myserver:8080/geoserver/wms
(..\..\..\..\..\src\core\raster\qgsrasterlayer.cpp : 668 : QgsRasterLayer::setDataProvider)

By sniffing the GetCapabilities request sent by QGIS using Fiddler, I get the following two layer definitions in return:

I have anonymized the messages above (since the error doesn't point in the direction of naming) and I can of course provide more information if needed.
