Used gdb to step into my onInit() function. Everything was fine till reaching getParam, after which the process hangs there.

void MyNodelet::onInit()
{
    bool rv = true ;

    ros::NodeHandle n(getNodeHandle()) ;
    ros::NodeHandle pn(getPrivateNodeHandle()) ;

    pn.getParam("Left Image Id", leftImgId_str_) ;
}

do you have spaces in your parameter name, or is a quirk of the markup language here? "test_space" Actually I really don't know if spaces are allowed in any way, but to remove them would be the first thing I'd try.

Yes, "space" is the cause of the hanging. Thank you! (I spent two days debugging it and couldn't find it. Thanks to your comment so that my weekend is not completely ruined)
