Strange, I can open without issues on SFOS, from terminal, as many times geo uri using harbour-pure-maps script. I wonder what does Qt.openUrlExternally do differently? Maybe this has to be uncommented: https://github.com/rinigus/pure-maps...aps.desktop#L7 ? For those with the bug, with desire to get into `devel-su` and test the fix, please do so.

PS: Probably would be way better when I integrate xXSparkeyy's PR into Pure Maps...
