Hi everyone I am using OpenSceneGraph-3.0.1 for a little project together with Qt-4.7.4 and it worked perfectly. After same updates on my system (I can't figure out what exactly changed) I get segfaults when starting either my app or the osgviewerQt demo.
Traceback from my app: Program received signal SIGSEGV, Segmentation fault. 0x0000000000841f0f in ?? () (gdb) bt #0 0x0000000000841f0f in ??

instead of nouveau. Can anybody reproduce this? Am I doing something wrong which worked by accident before?
