My YaST module uses two LogViews in one Dialog to display the status of system
daemon. The LogViews are defined as following:

Left(LogView(Id(:daemon_status), "VPN daemon status", 8, 0))
Left(LogView(Id(:conn_status), "All connection status", 8, 0))

Updates to the LogViews are made periodically (every three seconds):
Yast::UI.ChangeWidget(Id(:daemon_status), :Value, sh_daemon_status["stdout"])
Yast::UI.ChangeWidget(Id(:conn_status), :Value, sh_conn_status["stdout"])

where sh_daemon_status is the output of "systemctl status strongswan" and
sh_conn_status is the output of "ipsec statusall"

Several seconds after the dialog is opened, YaST crashes with segmentation
fault, see attachments for y2log and signal log files.

Very occasionally, instead of a crash with segmentation fault, y2base stops and
prints:
*** Error in `/usr/lib/YaST2/bin/y2base': malloc(): smallbin double linked list
corrupted: 0x00007fe36c30bf90 ***

The affected OS is openSUSE Tumbleweed.
