I'm connecting using http not https as my server's on the same machine.Are you using ca-certificate.crt? I was getting a start-up error with that so created a cert.pem file. That could be a red herring though.
Two suggestions:1) check the AUR PKGBUILD and makefile to see what files get placed, where.2) check the sourcode and makefile of the code you downloaded (from here https://github.com/bibinou/keepass2/tree/master/Build ??) to see if you can work out what gets put where.
Okay, I got it again on shutdown last night (it gets displayed on screen), but it doesn't appear in the logs. I do however have a segfault in the logs, that occurred during the shutdown process.The segfault was in xorg-launch-helper and the message was the first thing that occurred after X closed down. So yeah, I think I get it after segfaults, too.So, ignore my Cups comment above.
