Bug Description

Xubuntu 14.04.4 LTS
SSD is only drive (/dev/sda)
/dev/sda1 is boot partition
/dev/sda5 is encrypted LUKS partition
logical volumes sit on top of the LUKS partition

package: lvm2 2.02.98-6ubuntu2
problem type: Crash
title: lvm crashed with SIGSEGV in lv_is_merging_cow()

This bug is repeatable. If I create a LVM snapshot of lvroot (mounted to /) and run lvconvert --merge to restore the snapshot, after rebooting, this error report is generated.

However, if instead of running lvconvert --merge inside the system, I boot into a live ISO session and run lvconvert --merge, the process completes without any error being reported.
