simple-scan crashes when running simple-scan from the command line when simple-scan is already running

[Lyn Perrine]

To reproduce open simple-scan then open a terminal and execute simple-scan.

simple-scan:
  Installed: 3.26.3-0ubuntu1
  Candidate: 3.26.3-0ubuntu1

        100 /var/lib/dpkg/status
Description: Ubuntu Bionic Beaver (development branch)
Release: 18.04

I expected the original simple-scan to stay open when I ran simple-scan from the terminal with it already open. Instead simple-scan crashed.

Thanks for your report.

I reproduced a crash with your steps and reported bug 1748119 but could you get a stack trace to confirm you are facing the same issue? Thanks.
