What do you see in your Exclude if Present dialog? Just checked the code and not sure how this could be empty. Of course we can add another check anyways.

Can you check if

• The small change in Ensure no empty exclude-if-present is added #2136 fixes it?
• What's the content of patterns when the error happens in the same file? https://github.com/borgbase/vorta/pull/2136/files#diff-2559f308260b3597027f7b0650bc98f2783fbb1ed513a244a3ccb4756256d11cR173

@deermo Did you define the "exclude if present" using Vortas "Manage Exclude Items"?
Source>Mangage Exluded Items>Exclude If Present
The only way I could get this behaviour, using Vorta, is by at least putting one space " ", when adding a new "exclude if present" pattern. Without whitespace, no empty "exclude if present" pattern seems to be created anyway.
@m3nu I cannot test, right now - but the proposed change should indeed fix the issue, since, with the fix, the "exclude-if-present" is not created if the pattern contains only whitespace.

Sidenote: It is also possible to create custom exclude patterns with only whitespace " " in the "Custom" tab - but I guess in this case an empty (only whitespace) line in the --exclude-from file does not have unintended side effects.
