Qt Creator 2.0 displays additional warning information as errors

Follow-up from this discussion: http://lists.trolltech.com/pipermail/qt-creator/2010-July/007221.html

Build system used is qmake.
I don't know how to display stdout and stderr separately on the Windows commandline.

console output of gcc (presumable stdout?):
foo.h: In member function `void Foo<T>::bar(const T&) [with T = int]':
foo.h:137: instantiated from XYZ
foo.h:52: instantiated from XY
foo.cpp:18: instantiated from here
foo.h:60: warning: converting to `int' from `double'

> This warning is displayed in the "Build issues"-tab as
> (no symbol) In member function...
> (red exclamation mark) instantiated from XYZ
> (red exclamation mark) instantiated from XY
> (red exclamation mark) instantiated from here
> (yellow triangle) converting to `int' from `double'
>

Expected output:
Additonal informations t warnings should have yellow triangles or no symbol at all.
