+Subject: [PATCH] Qt UI: Fix partition count for APM disklabel
+
+The APM disklabel includes a meta partition for the partition map
+itself.  This is always counted by parted as a partition, and is *not*
+considered to be a metadata partition.  We therefore need to start our
+partitioning at #2 on APM, not #1.
+
+Closes: #376
