segfault with qt-facetrainer when clicking capture #106

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. run qt-facetrainer
2. click next
3. click capture
4. be sad

What is the expected output? What do you see instead?
Capturing my shiny face would be expected. :-)

What version of the product are you using? On what operating system?
up to date Arch Linux, and the svn version of PFA from the AUR. OpenCV is 
2.3.1-1

Please provide any additional information below.
I run it in GDB, so that there is somewhat more clue. Here is all the output:
(gdb) run

After the program quit, new, but empty directories appear under 
~/.pam-face-authentication/faces

This might be a problem with OpenCV. We actually should adapt the program to 
the new OpenCV C++ bindings. Currently the old IplImage style is used and I 
suppose some OpenCV internal conversion fails (as we aren't using cvarrToMat() 
at all)
