I'm experiencing the following error in the past few days.
File "/usr/lib/python2.7/site-packages/terminatorlib/terminal.py", line 1507, in feed self.vte.feed_child(text, len(text))
It turns out to be a known terminator bug, not by the plugin, as discussed here.
User can either wait for the new version of terminator, or patch the files manually. In my case (ArchLinux), I need to patch line 1507 of /usr/lib/python2.7/site-packages/terminatorlib/terminal.py to the following:
self.vte.feed_child(text)
I wrote here in case anyone need :)
