[regression 4.6.2->4.7.0] Black text on dark background

In 4.6.2, the Projects view respected the text color of the system theme.  In 4.7.0, the text color seems to be hard-coded to black, but the background is still taken from the system theme, which results in black on dark gray (hard to read).

I am using the "Classic" theme.

I found another bug reported on Mac OS, which might or might not be the same:
QTCREATORBUG-20494
