ofxGstreamer windows: exception in example

I have to work in Windows, and need to be able to receive a udp stream, and possibly udp rtp later. I am trying to use ofxGstreamer for this. I am using the latest version of the addon, and the instructions found here: ofxGStreamer windows10 setup instructions. After fixing some initial include issues, I’m now stuck with a null pointer exception when i try to run the example, the bug mentions the file:
\Microsoft Visual Studio\14.0\VC\include\xstring line: 1181

Solved by changing line 124 of the file ofGstUtils.cpp to
instead of only
And now the exception doesn’t happen anymore.
