Segmentation Fault using two cameras

[yagui]

I've tested the frame grabber plugin and with one camera it works great.
But I'm having troubles when I try to add a second frame grabber source. Sometimes the GUI crashes when I load the second camera source, and other times I can start recording but at the middle of the experiment the GUI crashes.
The only output in the terminal is Segmentation Fault so I really don't know how to start to debug it.
I'm using this branch https://github.com/yagui/FrameGrabberPlugin/tree/cmake to compile the plugin.

Thanks for pointing this out, I will wait for the author to reply before reconsidering using this for our experiments
