GUEST: Enter to properties and press on CSS preprocessors

GUEST: I've set a lot of path in CSS preprocessor

GUEST: Steps:
- installed SASS and changed default paths of SCSS and CSS folders
- unchecked the "compile SCSS on save" option
- left config dialog with 'Ok'
- when coming back to enable "compile SCSS on save" the config page of CSS preprocessors doesn't open (throwing the exception)

I likely clicked "add" without entering an additional path config. So maybe (not sure) there was an empty paths pair on the list.

Vitzkrieg: Not totally sure - updatnig JS libraries?

GUEST: I was removed the destination path from css compiled and dont put a new one, after that I close de popup and it never reopened again

GUEST: Wierd CSS processor config for less
