By some reason the regexp check for empty lines in the plugin code

        if line =~ '\(^\s*#\|^\s*$\)'
            continue
        endif

is not working in your environment. I just checked it with latest vim on a Linux machine with different regexpengine set (1 and 2): all variants work. You can try to play with this value setting in your .vimrc

set regexpengine=1

(or 2), but this is global! Probably your libpcre is something strange (do you use Windows machine?).

The easiest way to fix this is just remove empty lines in your xkbswitch.tr. ))
