Just triggered the problem with '1.1.3-0~ppa1raring'.
Steps:
. file->scan
. 'scan document' with 'fetching list of devices'
. then shows the hp deskjet at the other location that isn't reachable here
. main window shows 'opening device' at bottom
. 'scan document' window closes, and immediately:
. popup comes 'Error opening device: Invalid argument'
. close
. main window bottom still shows 'opening device' with a motionless ('stuck')
blue part.
. file->scan
. new window pops up with title 'Scan Document' and nothing in it
quit gscan2pdf and restart, same result.
console output:
$ gscan2pdf

I think the gdk_error_traps message has nothing to do with this problem,
it's a common thing for gtk apps, see #1075928
ps: i'm using a kde4 desktop.
