1) make sure you have a connection to a mock deltacloud server
2) select and image in the cloud view
3) choose "Launch instance" in the context menu
4) Launch instance wizard pops up
Result:
An error dialog pops up that tells you that no hardware profiles and reals could be loaded. The fact that these items could not be loaded is perfectly normal since mock server do not have realms nor hardware profiles.
Expected result:
No error is reported
