Less than 16 hours ago I improperly tagged 1.4_M5.rc1. If you have recently fetched updates from poky, eclipse-poky,  meta-intel, or meta-qt3 you will need to delete the bad tags.

From inside your poky repository run:

git tag -d 1.4_M5.rc1

If you see "Deleted tag '1.4_M5.rc1' (was c459a89)" then the tag has been correctly deleted.
If you see "error: tag '1.4_M5.rc1' not found." then your repository didn't have the bad tag and there is nothing else you need to do.

Repeat the steps for eclipse-poky,  meta-intel, and meta-qt3 repositories if needed. From inside of each repository run: git tag -d 1.4_M5.rc1

Thank you,
