To avoid crash I have replace CV_Assert(..) by assert(..).
But the next is not so good because I have the following message :
Invalid background description file.

So I will find it.

Hello Yannick,

Thank you for reporting the issue. Replacing CV_Assert to assert would'n help there=) If you could work on fix? a patch or a pull request in our repo would be very appreciated!
