GParted 1.4.0 on GParted live 1.4.0-1 activates LVM partition volumes on re-scan
Deactivated an LVM through the GParted right click menu, which automatically caused a re-scan by gparted. The "key" icon saying the LVM was active did not clear. Using 'lvscan' via the terminal confirmed that the volumes were still active. Manually deactivated the LVM volumes from the terminal via 'lvchange -an', verified via 'lvscan' that they were deactivated. Then re-scanned with gparted, the "key" icon did not clear and the 'lvscan' showed the volumes were active again.
