ofxUICanvas::setVisible crashes in latest build #250

I'm getting runtime errors when toggling visibility of a canvas -- only in the most recent nightly builds, not in 0.8.4. So presuming it may be an issue for 0.9.

void ofApp::setup(){
    gui = new ofxUICanvas("hello");
}
void ofApp::update(){
}
void ofApp::draw(){
}
void ofApp::keyPressed(int key){
    if (key=='1') {
        gui->toggleVisible();
    }
}

awesome!
can i also alert you to this issue i opened some time ago which may be related?
ofxUI often crashes the app if you try to remove widgets on mouse clicks (usually because it attempts to access the mouseReleased function of a widget which was deleted while the mouseReleased iterator is still running.
this makes it difficult to regenerate canvases, which would be a very useful feature. this is the only major issue i often encounter when using it, otherwise it's very stable.

@genekogan thanks! So the bug is fixed in the develop branch (working on updating the examples too), can you make another issue regarding the mouseReleased function / delete widget crash.
