debugger reports: HEAP[q3radiant.exe]: Invalid Address specified to RtlFreeHeap
( c00000, c48340 ) multiple times on exiting radiant.

I tracked this down to a call to g_free in QERApp_FreeShaders in shaders.dll. 
The corresponding allocation is in Texture_LoadTGATexture in radiant.exe, and 
is a qmalloc call.
