Yes, we "namespaced" the command-line property overrides, because there was potential for ambiguities, particularly between projects and products of the same name.
Your example should now read:

qbs products.unitTestRunner.showCoverageData:true

The other possible prefixes are "projects" and "modules".
We should probably emit a warning if the prefix is missing; I'll make a note.
