Crashes Sites in Debug mode

Since the last Update there occurs a problem for sites that run in debug mode.

The problem:

Every time the website is loaded osm creates an error messages (see details at the end of this page):

... Called osm_restrict_mime_types filter.
... Allowed MIME types after modification: Array

In our case it filled up the debug-logfile with over 80MB Logdata within 8 days! That means that all local services, that run on the dashboard that help to show the logfile will create critical errors since the logfile is too big. Important other log messages are almost unvisible since it is totaly spamed.
