There are two cases where a maintainer cannot promote a package because it depends on a not yet promoted user package.
eSpeak GUI Client 0.1-5 has 19 Karma but it depends on espeak-extra-data.
FCamera 0.1.3-1 has 12 Karma but it depends on fcam-drivers.
The second might show a bug, since fcam-drivers has 3 super tester votes but is not unlocked for promotion.

How can this be more clear for testers?
