(Sorry for being so slow to cooperate on this bug. I only have access to this computer from time to time.)
I installed gscan2pdf 1.4.0 from the Ubuntu yakkety repository and it crashes as soon as I start the application. On the command line, I get: > gscan2pdf > Can't use string ("gimp %i") as an ARRAY ref while "strict refs" in use at > /usr/bin/gscan2pdf line 4160. > Perl exited with active threads: > 2 running and unjoined > 0 finished and unjoined > 0 running and detached Gimp is installed on the computer.
