The colony bug Master Belisarius described is new and it's a quite nasty one.

It MAY be related to one known problem:

For example, you have several "attack ship" designs in "AI_design.txt" file. Now, if you call for "attack ship" in "creation_vehicles.txt" txt file, AI will build only the design it first encounter - the one closeset to the begining of design.txt file.

The same could happen with colonizers. If you have:
Colony Rock
...
Colony Ice
...
Colony Gas
...
in design.txt file, AI will build only Rock colony ships ! I know it should not happen - AI treats colonizers differently than other ships, but it still can happen. "colonizer dead ends" is a very good example ! I suggest to reorganize design.txt file. For example Rock races should have Rock colonizers at the bottom. May be it will help.
