Comment 21 for bug 659106

If more testing or verification is needed please say so. Be sure to check the duplicate as I attached logs there.

I can assure you that this is 100% reproducible if only primary partitions are present, which is what most Windows users would encounter.

If an extended partition exists it's a crap-shoot. Sometimes it will actually use the "entire partition" as selected, but sometimes it will wipe the whole disc!
