Comment 6 for bug 1615629

Thanks for investigating this!

It seems that the pygtkspellcheck version that fixes this issue is version 4.0, released on 2012-10-01. Unfortunately, Ubuntu 14.04-16.10 have version 3.0 and only Ubuntu 17.04 will have version 4.0.5. This means we'll probably have to add a copy of pygtkspellcheck 4.0.5 to RedNotebook. Or does someone see a better solution?
