How to rebell correctly?

[Fixiwee]

Rebellion CTD's are apparently caused by lack of recruitment options available (i.e the game is unsuccesful trying to spawn an army to take over your city).

Okay so does that mean I need a barracks or what?
Because in some cases it worked, it's only certain cities.
Hmm maybe because I destroyed the foreign MICs?
This is confusing me. ;(

Edit: Well so I tried to apply aux. MICs to help the rebellions get an army (oh the irony!), but that didn't help.
