Usage of the kpartx package to create partition names has been
completely removed. Hence kpartx is no longer even an optionally used
package by gparted.
This change is related to the following bug report:
Ubuntu launchpad bug 719129 - [Natty] Gparted duplicates dmraid
partition devices
https://bugs.launchpad.net/ubuntu/+source/gparted/+bug/719129
The new configure option --enable-libparted-dmraid enables the native
use of /dev/mapper dmraid support in the libparted library.
If this option is not specified, or is disabled, then gparted code
will be used to support dmraid. The gparted code uses the old dmraid
partition naming scheme of always appending the partition number to
the device name. The letter 'p' is not inserted between the device
name and the partition number. The gparted code is particularly
useful when used with older versions of libparted that do not support
/dev/mapper dmraid.

Added a display refresh to the event queue to address this
problem.
Previously, the display area of the visual disk seemed to
disappear when enough operations had been added to the queue so
that a scrollbar was required (about 4 operations).
If the three lines in HBoxOperations::load_operations method for
"//make scrollwindow focus on the last operation in the list"
were commented out then this also prevented the problem from
occurring.
Interestingly, if I changed the "set_cursor" method to
a "scroll_to_row" method, then this problem does not occur for an
additional 2 operations (about 6 operations total).
