Sentry Crash Report:

Description cromachina 2025-02-05 22:47:30 UTC 
SUMMARY
Attempting to export an animation sequence from the command line results in an error if the exported files already exist. This does not happen when exporting a non-sequence, single image.

STEPS TO REPRODUCE
1. Make a document with an animation in it: test.kra
2. Exit Krita (cannot export with Krita open due to another bug https://bugs.kde.org/show_bug.cgi?id=460631).
3. Export the document's animation:
  krita --export-sequence --export-filename test.png test.kra
4. Run the same export command again (as if you had edited the document and wanted to update the output).

OBSERVED RESULT
krita.general: "Failed to render animation frames!" 

EXPECTED RESULT
The target files are overwritten.
Or, if this is not acceptable, then a more clear error could be given like: "Failed to render animation frames! Output files cannot be overwritten with export-sequence." 

WORKAROUND
Delete the files before running the export command.

CLI/Animation: Fixed failure to overwrite existing animation sequence.

Exporting animation sequence from the command line no longer fails
when frames already exist in the target directory.
