Description
The following Python code shows how the destination CRS isn't set the 2nd time:
crs = QgsCoordinateReferenceSystem()
crs.createFromProj4('+proj=tmerc +ellps=WGS84 +datum=WGS84 +no_defs')
iface.mapCanvas().setDestinationCrs(crs)
iface.mapCanvas().mapSettings().destinationCrs().toProj4()
crs = QgsCoordinateReferenceSystem()
crs.createFromProj4('+proj=tmerc +ellps=WGS84 +datum=WGS84 +no_defs +lon_0=1 +lat_0=1')
iface.mapCanvas().setDestinationCrs(crs)
iface.mapCanvas().mapSettings().destinationCrs().toProj4()

It looks like the issue is a naive QgsCoordinateReferenceSystem == operator.

I'll try to create a patch.

Nevermind, I should be create a custom QGIS CRS with a unique QGIS CRS id. Can someone please cancel this?
