"Unable to open attachment" for ZIP files
I was sent an encrypted PDF file with several attachments in it. Most of them are ZIP files. Nothing happens when left-clicking on them. When trying to open them via right-click -> "Open Attachment" an error is shown "Unable to open attachment: Couldn’t open attachment “/filename.zip”: Failed to execute child process “file-roller” (Permission denied)".
I am able to save all attachments via Okular.
