Good to know.

You mean the path frontends/qt4? This is indeed confusing, but it is
just the path of the files. It does not actually mean anything about Qt4
and in 2.4.0dev we've renamed the directory to just "qt" so the path
will now be "frontends/qt".

In that case, it could be that the fix referenced above actually made
things worse for you. You could try to revert the commit 7a158055 on the
2.3.x branch and see if that makes the terminal message go away for you.
If you do that, please let me know if it helps things because that means
we should fix something.
