I just got this error on Config file I have configured few weeks ago. I checked the log file to see after which channel grabbing crashed and then I head to config and checked location of that channel and everything seems fine. No spaces, holes, accidentally typed characters or similar. It's a properly configured config with channels.

Absolutely nothing was changed in config for weeks as said. I will run another grabbing process and update this issue. I would just like to know what is this about. Some strange characters and words are here in log.
