ok now it just crashes if --clear-settings is not used, seems like 1.4. does not need to be opened inbetween

[nitrosimon]

also crashes when:

removing a Nitrokey unlocking password safe lock password safe sometimes opening the about page after opening the app very fast and closing it again crashes the app

the actions are always performed though and the app is closed immediately afterwards
