SCH 2.6.0 & WP 3.9: Default language data won't load

After updating crayon seems to be unable to find the default language data.

My log is full with:

[SYSTEM LOG] 'Upload directory is empty: ' [SYSTEM LOG] 'The resource directory is missing, should be at \'\'.'
[CrayonUtil::lines()] 'Cannot read lines at \'default/default.txt\'.'
[SYSTEM LOG] 'The language at \'/langs/c/c.txt\' referred to the Default Language regex for element \'COMMENT\', which did not exist.'
[SYSTEM LOG] 'The language at \'/langs/c/c.txt\' referred to the Default Language regex for element \'PREPROCESSOR\', which did not exist.'
[SYSTEM LOG] 'The language at \'/langs/c/c.txt\' referred to the Default Language regex for element \'STRING\', which did not exist.'
[SYSTEM LOG] 'The language at \'/langs/c/c.txt\' referred to the Default Language regex for element \'STATEMENT\', which did not exist.'
[SYSTEM LOG] 'The language at \'/langs/c/c.txt\' referred to the Default Language regex for element \'RESERVED\', which did not exist.'

The default folder is in the ‘langs’ folder and readable. Before the update the fallback was working.
