Hi Christian,

i think i narrowed down the problem. However, i think i should give you a
quick overview of my compiled in functions of vim and my system.

I tried it on three different machines, but all running Archlinux x86_64.

I created an new user and tried to reproduce the error building a vimrc from
scratch. It turns out that you can reproduce this error with only two options
set:

filetype plugin on
set cursorcolumn

However, this error only occurs when you have the preview option of
omnicomplete enabled an try to auto complete something that will force the
preview window to pop up. Having the +python option compiled to your vim, the
easiest way would be to open a *.py file and type something like the following:



import sys

sys.


After the sys. try to invoke the auto completion with <C-X><C-O>, if the
preview window won't pop up try to set

:set completeopt+=preview


I hope this'll help you to reproduce the error. By the way, you can leave the
preview window open and disable the preview option via

:set completeopt-=preview

and the list will appear.


Best regards,
