I have the same issue on my laptop with a FireGL T2 card and i586 since at least two years, likely longer. If there is any osgText in the scene, the viewer locks up in a busy loop, pegging the CPU at 100% load. Usually it wakes up after several minutes, though, without a reboot. I believe that it has to do with the way osgText is implemented - by rendering glyphs into many small textures which need to be generated and uploaded to the GPU when the node is first time rendered. The subsequent triggering of stats or help is immediate for me, only the first one is always a problem. I have "solved" this issue by implementing my own text widget using Cairo and Freetype. That way I have only a single quad with a single texture, regardless of how many characters and with what font I render.
