Package: gscan2pdf
Version: 2.13.0-2
Severity: normal
Tags: upstream

Hey,

for every page processed by unpaper, I get two errors:

1. [image2 @ 0x558772ceee40] The specified filename 
   '/home/ssd/madduck/.tmp/gscan2pdf-SMFz/OHSkXwKy5v.pnm' does not 
   contain an image sequence pattern or a pattern is invalid.
2. [image2 @ 0x558772ceee40] Use a pattern such as %03d for an image 
   sequence or use the -update option (with -frames:v 1 if needed) 
   to write a single image.

Okay, but gscan2pdf makes it an error, and I do wonder if it's 
possible to hide them…

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