I think I've localized the problem.
Looks Linux unable to deal with GPT pure partition tables (without synced MBR).
In past a patch (gptsync.patch) was added to parted to solve that issue. (Not sure ubiquity should enjoy from that fix also)
But it looks like parted refuses to sync GPT and MBR, even tried to force it by "PARTED_GPT_APPLE=1 parted".

Above also correct for OSX Graphical Disk Utility. Console version of OSX diskutil does create GPT with synced MBR.

Since the issue is not related to specific system, incomplete status should be removed.
Hope there is a solution floating in upstream...
