As a note, upstream has completely ignored the bug report about this on their mailing list:

    https://www.riverbankcomputing.com/pipermail/qscintilla/2016-October/001160.html

Looking through their archives, they seem to ignore 95% of everything. Would recommend steering clear of QScintilla2 for new projects. 😦

@justinclift is it possible there's some other mechanism for contacting/reporting other than the mailing list?

[justinclift]

Their support page directs people to the mailing list, and also says:

Unless you are a commercial customer, do not email Riverbank directly.

So, I'm thinking no?

You are buying 1 PyQt commercial license at £350.00.

If they're going to ignore anyone who hasn't given them $429.00, then it sounds like the project needs to be forked or not used. I suspect it's worth emailing [email protected] and hoping they don't look a gift horse in the mouth since macOS is one of their officially supported platforms for paying customers.

Hmmm, I'll give it a few more days before doing that. Just in case.

[ilovezfs]

Yup, no problem.
