Hi, i want to test pam-face-authentication

What steps will reproduce the problem? 1. emerging v0.3 from kde overlay or compiling source file from project page 2. starting qt-facetrainer

What is the expected output? What do you see instead? qt-facetrainer starts, if i click on next it exits with a segmentation fault dmesg: qt-facetrainer: segfault at 1 ip b6009e58 sp bfbdf4a0 error 4 in libgobject-2.0.so.0.2800.6[b5fe0000+43000]

What version of the product are you using? On what operating system? Im using version 0.3 of the software OS = gentoo linux with kernel 2.6.38r4 and gnome 3 opencv version is 2.1.0 (pfa wont compile against 2.2.0) qt versions are 4.6.3 and glib (to which /usr/lib/libgobject-2.0.so.0.2800.6 belongs) version 2.28.6 with introspection support (use-flag)

okay I got it run with svn source and opencv-2.0.0. The new problem is, that opencv<2.2.0 cant be build against linux-headers-2.6.38 with v4l use flag (known issue). And without v4l useflag, my camera isnt accessible in qt-facetrainer.
