#1912 Could not set X locale modifiers
I ran a fresh installation of keepass 2.38 (installed via Ubuntu repositories) on a fresh installation of Ubuntu 18.04.3. It crashed when I tried to open a database. I'm not sure why, and I doubt we'll be able to figure that out. However, when I tried to run keepass again, I get this on the terminal output:
$> keepass2
Could not set X locale modifiers
Keepass did not open.
The issue was resolved by running this:
$> rm -Rf ~/.config/.mono
Apparently, this message is generated when the call to Xlib's XSetLocaleModifiers fails.
This is clearly a bug in Mono which is affecting KeePass users.
