That could very well be, but volunteers who devote their spare time to help
may have a policy to only start helping you when you have upgraded to the
latest version. In general it avoids wasting time on already solved issues.

It could be that upgrading doesn't help, but things may also have happened
in SCons that could affect this. If you still see the problem after
upgrading you'll likely get the help you need.

Regarding the error, it's similar to an issue I saw myself when switching
to python 3. SCons has two ways to get the content of a file, one returns
text (python unicode), and the other returns bytes. If that's the problem,
swapping out calls to get_contents() with get_text_contents() might help in
the tool source code.

I see you are using an external qt tool instead of the one that ships with
scons. I think the qt tool that ships with scons supports Qt5 now, so you
could consider trying it instead of this possibly unmaintained tool.

Cheers,
Thomas
