The `uris_as_paths` member, which is set to `true` when the paste command has been triggered by the **Paste Filenames** action, was being checked too late: a file URI was ultimately being entered to the terminal, as opposed to the expected plain text version. Test plan: - Copy a file in Caja, or in any other file explorer that inserts the `text/uri-list` and `text/plain` MIME formats into the clipboard. - Paste the file in a MATE Terminal either via `Ctrl+Shift+V`, or via the **Paste** action in the context menu. Without this change, a file URI is entered. For example: ``` file:///home/jane.doe/my%20pictures/foo%20bar.jpg ``` With this change, a regular filepath [that the filesystem can recognize] is pasted. For example: ``` /home/jane.doe/my pictures/foo bar.jpg ``` Note that the behavior of the **Paste Filenames** context menu action remains unchanged (i.e. file URIs are still converted to regular paths surrounded by single quotes).
