Open launcher (lists all applications sort of like the Start buttone on Windows). Right button click on icon of app to autostart and select 'Add to startup'
/var/tmp/pamac-build- has directory for each downloaded package. is a userid having the issue (i.e. /var/tmp/pamac-build-kurtis/).
Removing the directory of the package fixed the problem.

Make sure the Software manager tool is enabled for AUR packages (see app settings). The editor that shutter uses is in the AUR repo. Install the package perl-goo-canvas and the shutter editor should now work.
