Using with highlight-indent-guides

[lockie]

Hey. Using poly-mode with highlight-indent-guides constantly spams errors into *Messages* buffer about font locking. Using toggle-debug-on-error gives a following backtrace:

Debugger entered--Lisp error: (args-out-of-range 8127 #<marker at 6927 in  player.org[lisp]>)

Should it be reported to h-i-g bugtracker?..
