I'm developing a multi-platform application that is using a systray icon in SVG format.

Everything worked fine under Qt 4.x and Qt 5.x until Qt 5.3.2 but since Qt 5.4.0 (so including 5.4.1), my SVG icon is completely invisible, nothing is displayed in systray, but the space is reserved because I can click on the "blank" icon.

I wrote a minimal test case to reproduce the bug.

I tried it under OS X 10.10 compiled with some Qt versions :

• Qt 4.8.6 - working
• Qt 5.2.1 - working
• Qt 5.3.2 - working
• Qt 5.4.0 - broken
• Qt 5.4.1 - broken

In all cases, I compiled Qt 5 myself in static with :

./configure -qt-harfbuzz -release -opensource -openssl-linked -opengl desktop -static -nomake examples -nomake tests -nomake tools -system-zlib -system-libpng -system-libjpeg -no-c++11 -confirm-license -no-glib -no-icu -I /opt/local/include -L /opt/local/lib

For 3rd party libraries (zlib, libpng and libjpeg), I'm using those from MacPorts.
