appimage debug log from start to crash

Using appimage 

app: digikam-5.9.0-01-x86-64.appimage 
linux version: Linux darkstar 4.14.59 #1 SMP Sat Jul 28 14:22:58 CDT 2018 x86_64 
cpu: AMD Ryzen Threadripper 1950X 16-Core Processor AuthenticAMD GNU/Linux
graphics drivers: NVIDIA Linux drivers x86_64 version 396.45
filesystem: type nfs (rw,user=root,noexec,nosuid,nodev,hard,intr,rsize=8192,wsize=8192,timeo=14,addr=192.168.1.3)

The last state of the app is like this image https://i.imgur.com/WKmxcHE.png. The last click was to the date selected.

Using appimage debug option, the stack trace is:

Thread 66 "Thread (pooled)" received signal SIGSEGV, Segmentation fault.
