** Description changed:

+ [ Impact ]
+ 
+  * Errors that occur while running postprocessing scripts in simple-scan will 
be erroneously reported as save failures instead, leading the user to believe 
their file has not been saved.
+  * Scripts that output into stdout and stderr are supposed to have this 
echoed to the terminal when running with simple-scan --debug, but do not.
+ 
+ [ Test Plan ]
+ 
+  * Run simple-scan with `simple-scan --debug test`.
+  * In the Preferences menu, enable postprocessing.
+  * Set the path of the postprocessing script to a non-existent file.
+  * Attempt to save a scanned file. Saving should succeed, and the 
postprocessing error should get a popup with the title "Failed to run 
postprocessing" and a description stating the actual error.
+  * There should be no popup if the postprocessing succeeds.
+  * Error codes in the postprocessing script itself should not result in an 
error popup, only if the provided script path is incorrect or inaccessible.
+  * Anything the postprocessing script prints to stdout and stderr should be 
reflected in the terminal running simple-scan.
+ 
+ [ Where problems could occur ]
+ 
+  * Logic around saving has been changed, so there might be possible
+ regressions when saving without postprocessing enabled, and this
+ scenario should be tested.
+ 
+ [ Other Info ]
+ 
+  * This bug has already been fixed upstream, and the changes here are
+ cherry-picked from there: https://gitlab.gnome.org/GNOME/simple-
+ scan/-/merge_requests/290
+ 
+ [ Original Description ]
+ 
  Release: Ubuntu 24.04.2 LTS
  
  Simple-scan version: 46.0-0ubuntu2
- 
  
  When saving a file, simple-scan warns that the file cannot be saved, even 
though the file is actually saved.
  Then saving is proposed when I quit simple-scan and I have to quit without 
saving.
  
  It's not blocking, but it's annoying all the same.

  I found this answer that solves the problem: https://askubuntu.com/a/1411037
  So it seems like the problem is post-processing.
