Comment 34 for bug 1902801

Tested with 78.6.0 Linux, unfortunately the decrypted files are saved incompletely.

I received two small PDF documents. I clicked "decrypt and save as", but on my filesystem the files have only few bytes. Nothing appears in the error console. I have successfully checked decrypting the pgp-files with gnupg.
```
$ gpg -o Abrechnungsschreiben_6912.pdf-gnupg -d Abrechnungsschreiben_6912.pdf.pgp
$ gpg -o Antragsnummer_79282.pdf-gnupg -d Antragsnummer_79282.pdf.pgp
$ ls -l *pdf*
