Yup. This patch fixes things:

I just tried with the patch applied, and I still get

[image2 @ 0x5609ccef9e40] The specified filename
'/home/ssd/madduck/.tmp/gscan2pdf-uiWw/eLwbJ_5EFR.pnm' does not
contain an image sequence pattern or a pattern is invalid.

Looks like temporary files can have underscores as well. Please try this 
instead (word instead of alnum).

to hide them…
