Compiling qt with the desktop an es2 opengl backend works. Compilation fails with the es1 backend.

When I try to start a program with the opengl backend I get the following errors:

qt compiled with es2 opengl system:
  $ dolphing -graphicssystem=opengl

Got 3D working in general. Have a look at bug report 30412.

Now I get the following error with opengl es2 backend:
dolphin: symbol lookup error: /usr/lib/egl/egl_gallium.so: undefined symbol: drmGetMagic
<unknown program name>(19415)/: Communication problem with  "dolphin" , it probably crashed. 
Error message was:  "org.freedesktop.DBus.Error.ServiceUnknown" : " "The name org.kde.dolphin was not provided by any .service files" " 

This seems to be the same error as in Bug 30401. I think these two bugs can be merged.
