It seems we are missing something in the XML definition file for QLGT, here
you can see a transcript of part of the dialog between QLGT and the server:

Request from QLGT to the server

Host: gis.lmi.is
GET 
/viewsvc/gogn-isn93/haedargogn-isn93/MapServer/WMSServer?request=GetMap&version=1.3.0&layers=Haedargogn_punktar_IS_50V&styles=&srs=EPSG:4326&format=image/png&width=1024&height=1024&bbox=-19.633169,64.588312,-19.065458,64.918446


Response from the server

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<ServiceExceptionReport version="1.3.0"
  xmlns="http://www.opengis.net/ogc";
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
  xsi:schemaLocation="http://www.opengis.net/ogc 
http://schemas.opengis.net/wms/1.3.0/exceptions_1_3_0.xsd";>
  <ServiceException code="InvalidSRS(CRS)">
Parameter 'srs(crs)' can not be empty.
  </ServiceException>
</ServiceExceptionReport>


And in fact, the URL above doesn't include the "&crs=CRS:84" parameter that
should be there, as it is defined in the GDAL XML definition file, and
looks fine according to [1].

I have tried two things, with the exact same result (QLGT asks for the
tiles, the server no longer complains, but tiles are blank). The first
attempt has been by changing your XML definition file, to "downgrade" to
WMS version 1.1.1, and remove the "CRS" tag.

The other attempt has been at hand crafting the URL using WMS 1.3.0 and
adding the "&crs=CRS:84" parameter to the original URL, but I still get
blank tiles.

Please try the first approach on some parts of the map coverage, I may be
looking at wrong coordinates or outside the map's bounding box.

Cheers.
