After Ubuntu (MATE) 16.04 it's not possible to sign multiple files with Kleopatra. All versions from Ubuntu (MATE) [x64] 18.04; 19.10, 20.04 tested by me are affected. After selecting two or more files, Kleopatra inevitably crashes. I can only sign one file at a time without Kleopatra crashing. I use Gpg4win 3.1.11 with Kleopatra, in addition to Linux, also under Windows. There are no problems with the signature of multiple files here. I use Kleopatra because it is not possible to sign multiple files in GnuPG. I am now using Ubuntu 20.04. The problem also exists here. STEPS TO REPRODUCE 1. Copy three files into the download folder to be signed. 2. Open Kleopatra. 3. Click the button: "Sign / encrypt" 4. Open the "Downloads" folder. 5. Select all three Files (CTRL + A) 6. Press the button: "Open" 7. Kleopatra now crashes. EXPECTED RESULT Kleopatra should create several * sig files. Instead, it crashes. SOFTWARE/OS VERSIONS Linux: Ubuntu MATE 20.04 (Tested with a new and fresh installation!) ==> Kleopatra makes handling GPG a lot easier. Thanks for that.
Created attachment 140471 [details] Screen-Video about this bug Test on Ubuntu 21.04. I have created a Screen-Video that describes the Problem detailed. After Ubuntu 16.04 LTS - it's not possible to sign multifiles with Kleopatra! No Problems by Kleopatra under Microsoft Windows.
