scanning multiple pages from flatbed results in error message but scan works

[Andreas]

when I select "Multiple Pages From Flatbed" it results in an error message after every page
(screenshot attached) - Failed to scan - Unable to start scan [close] but it works well.

so.. probably cosmetic.

by the way: This application is dope - 100 times more accessible than xsane ^ ^
