[TkD] X11 Error(Possible bug?)

[Jack via Digitalmars-d-learn]

Complete error code here: http://codepad.org/KcW7jhXl
Apparently, there exists an incompatibility.
Take note, I just listed tkd as a dependency on my dub.json, and 
I haven't really used the library as of the time of its building.
So, is this a bug?
