This might be one of the strangest bugs I ever had. I’ve been using KDEs Vaults feature for quite some time now, to encrypt some important documents. But since a few weeks ago, everytime I unlock a vault LibreOffice starts and I have no idea why. It doesn’t do much, just showing the welcome screen where I could select a document to open. Besides from that the vault unlocks just fine and is mounted. However it does not open a file browser automatically.
