I have an bug message when open Gparted program. Here is the error:

Before that I Changed "System Reserved Primary Partition" of Windows 8. I formatted that partition and made it Logical and than deleted, because there was another partition "C" in which System and Boot Files were placed. So I made that partition unallocated.

While I came to my Linux GParted it showed that error or bug. Can anybody help me what should I do? I uninstalled GParted and than again installed but problem was not solved.
