when loading a incomplete file, I never get a picture, often it results
in a segfault (when calling m_Mutex.Unlock(); line 1790 in renderer.cpp,
however somehow this call ends up somewhere in the SDL code):
Other times it simply exists with code 0 right after writing:
"<renderer> : Loading subfont blablabla"
a classic race condition?
