Hi Mario,
Thanks for the through testing. I have a dual core Linux box myself
but alas hadn't seen threading problems before with osglauncher, but
then its not an example I generally hammer.
My guess is that the updating text is not being guarded as being
dynamic so is ended up being modified whiles still being read by the
rendering threads in the DrawThreadPerContext and
CullThreadPerCameraDrawThreadPerContext cases.
To fix this I have added in an explict setting of the data variance to
DYNAMIC via;
updateText->setDataVariance(osg::Object::DYNAMIC);
osglauncher is stable for me, but then it was stable before... Could
you do a svn update and let me know how you get on.

Thanks Robert!
Now osglauncher (almost) works.
But if I simply move the mouse around on the osglauncher(d) window,
after a while I receive a segmentation fault.
To reproduce:
- run osglauncherd (the crash happens in or outside gdb)
- move fast the mouse on the screen over the various thumbnails so the label
on screen changes
See the attached gdb stack trace.
If I set OSG_THREADING to:
SingleThreaded no crash
CullDrawThreadPerContext no crash
DrawThreadPerContext chash, sometime as soon as app loads
CullThreadPerCameraDrawThreadPerContext crash
Platform is Linux32 with GeForce 6800 GS and driver 8762
and two dual core Xeon
Hope it helps
