I have the same issue on my working machine, but I could not reproduce it at home or anywhere else, so I decided that it is an issue of my six years old system after crazy live migration from funtoo with qt4 to gentoo with qt5.
I fixed it a bit differently; replaced with a function, which returns the same static var.
