First of all you must to stay calm. The second thing you can do is
make this same query in TeX StackExchange which is the most relevant
place to ask anything related to TeX.

However, in the meantime, it seems that something related to R crashed
in Fedora, you recently just upgraded some related package?

What version of TeXlive you have installed?

Have you tried to download from the CTAN TeXLive 2014 and install it?

Is the problem that you relate, generally with any document or one in
particular?
