There is no particular reason, why VALA_MIN_API_VERSION is set 0.30. midori has no problems at all building with older vala versions. This gives certain troubles, whn you restricted in vala version (for personal reasons). Please, reconsider this requirement or at least give enough information why it's set. Reproducible: Always
