Original Redmine Issue: 7690
Affected QGIS version: master
Redmine category:web_services_clients/wms

In QGIS trunk (3bd21bc):
If I try to add a WMTS service with multiple dimensions, only odd lines are displayed with content (see screenshot).

!qgis_wmts_dim_select.png!

If I press OK, QGIS crashes.

Extract of GetCapabilities (with dimensions)
(Service provided by Mapserver Mapcache)

Not yet, but I can make something up for testing... (I just need a little time ;-) )

Here you go: http://193.34.136.206/mapcache/wmts?service=wmts&request=getcapabilities&version=1.0.0
This service has two dimensions...
(demo: "here":http://193.34.136.206/mapcache/demo/wmts)
Tiles aren't pregenerated, and distant WMS is busy, so.. it'll be slow, but will expose the problem in QGIS.
Thanks for your time!
