Minimal test case

I installed Arch Linux base system...
Then I installed vim...
Then I installed xorg...
Then I installed firefox...
Then I installed python... ( python3.6 in Arch Linux )
Then I installed i3-gaps... ( by Arch AUR repository )
Then I installed youcompleteme vim plugin through vim-bundle...
Then I installed cmake, clang, llvm, gcc-fortran, clisp, lua by pacman...
Then I compiled youcompleteme by

sudo python install.py --clang-completer --system-libclang

Then I tired...

vim test.py

and typed stuffs...
Then I got this error. Ycm isn't working and
something poped up very fast and dissapeared in status bar.
I checked it out with :message command and it says...

HTTPError: 500 Server Error: Internal Server Error for url: http://127.0.0.1:58983/completions

I got this error right after changing my desktop environment to i3-gaps.
I was using xfce4 before and it worked well back then...

Thanks for the detailed report. Completion for Python 3.6 is not yet supported by YCM. We need to merge PR ycm-core/ycmd#686 then update the ycmd submodule for that.

Fixed by PR #2495.
