After upgrading gedit from 3.18.0 to 3.18.1 synctex stopped working.

It seems a change in the API (that should not happen in a stable release!) or maybe it is just me :-)

It turns out that doc.get_iter_at_line() now returns a tuple instead of just an iter.

I do not know if the change was actually intended or accidental. Therefore, I am not providing a proper patch.

It would be great to get some sort of feedback when a plugin is broken. The UI does not say anything, nor disable the plugin that is unable to load.
