Solution if you want to fix it permanently yourself without patching udisks - see Bug #1093901 comment #3 - worked for me.
- Problem was nested extended partition
- Easy check that you are affected - sudo fdisk -l /dev/sda (if problematic disk is /dev/sda) returns first row "omitting empty partition (5)")
- Proper check - sudo dd if=/dev/sda2 count=1 | hexdump returns only 1 extended partition with type 05 (if extended partition is /dev/sda2)
