Any thoughts?

ender672 commented 11 years ago

This looks very similar to #845 which was fixed in the master branch by 287a6ca. This fix isn't in a released version of nokogiri yet. Can you test the failing script against the master branch?

I have the exact same bug in 1.6.2.1 in diaspora, see stacktrace at https://github.com/diaspora/diaspora/issues/4989#issuecomment-45982787

I guess the fix is already merged, so there still is a problem. Will try to find what xml was malformed.
