Jekyll failing with:
Liquid Exception: Failed to get header. in _posts/filename.md/#excerpt
/home/philipp/.rvm/gems/ruby-2.0.0-p247@global/gems/pygments.rb-0.5.0/lib/pygments/popen.rb:358:in `rescue in get_header': Failed to get header. (MentosError)
from /home/philipp/.rvm/gems/ruby-2.0.0-p247@global/gems/pygments.rb-0.5.0/lib/pygments/popen.rb:338:in `get_header
Tracked it down to mentos.py. Running mentos.py gave me the following error:
$ python mentos.py

Some time ago I installed (and removed later) bugwarrior via sudo easy_install bugwarrior
And for some reason mentos.py insisted on using the oauth package in /usr/local/lib/python2.7/dist-packages/... I removed that and now jekyll is running again.
