[QScintilla] Bug copying text on QScintilla

[Scener Spanish]

Phil, that workaround sounds great!

When I'm back home I'll check it out to confirm it'll work with this and
the mcve provided in the other thread in pyqt mailing list. In the other
thread you'll see when using pyside you don't need explicitely delete the
app.

In any case, my main goal was making sure you would become aware of this
one :)

Thanks for looking into it
