[Qt-creator] QFileDialog with error "Couldn't open named pipe (2)"

[Ballig]

Apologies in advance if this is not an appropriate forum for this question - please point me in the direction of one if that is the case.

I am using Qt Creator on Windows XP 64-bit and receive the error "|tid<number> Couldn't open named pipe (2)" in my application output when opening a QFileDialog - doesn't appear to matter what options I set, or how I open it.  I have tried QFileDialog::getOpenFileName() as well as creating a new QFileDialog object.  I seem to get one line of that above error for each file in a directory, although I appear to be able to use the file dialog without issue. I get the messages when the QFileDialog is first opened, and whenever the directory is changed.

Hope someone can help.  Thanks.
