Have the same Problem with different Setup:

• OS version: Ubuntu 18.04.4 LTS (cat /etc/os-release)
• Mono version: 6.8.0.123 (mono --version)
• KeePass version: KeePass 2.44 (keepass2 --version)

Have started keepass with mono on terminal. After i clicked on "Tools -> KeePassNatMsg Options" the following error occurs:

$ mono KeePass.exe 

[xcb] Extra reply data still left in queue
[xcb] This is most likely caused by a broken X extension library
[xcb] Aborting, sorry about that.
mono: ../../src/xcb_io.c:577: _XReply: Zusicherung »!xcb_xlib_extra_reply_data_left« nicht erfüllt.

sorry for taking so long on this - i don't use linux an my primary os, but i'll have a look at this soon.

also, i'm guessing that keepass runs fine when the KeePassNatMsg plugin isn't installed?

this might be a lead: kee-org/keepassrpc/issues/81

i'll do some more investigation later today.

edit: there might be a few problems going on here. i think one is missing mono packages (installing mono-complete changes the error). the second might be related to the issue noted above.
