Animated GIF Problem

[MSUdom5]

This one is really giving me a headache. I'm loading an animated gif and setting it as a movie in a QLabel.

QMovie *status_gif = new QMovie("status.gif");
 
	if (!status_gif->isValid()) {
		QMessageBox::information(this, "Error", "This Sucks...");
	}
 
	status_gif->start();
 
	_status_animation = new QLabel();
	_status_animation->setMovie(status_gif);
	_status_animation->setFixedSize(31,31);
	status_layout->addWidget(_status_animation);

QMovie *status_gif = new QMovie("status.gif");

	if (!status_gif->isValid()) {
		QMessageBox::information(this, "Error", "This Sucks...");
	}

	status_gif->start();

	_status_animation = new QLabel();
	_status_animation->setMovie(status_gif);
	_status_animation->setFixedSize(31,31);
	status_layout->addWidget(_status_animation);

To copy to clipboard, switch view to plain text mode 

This works great on my machine (the one I wrote the code on), but on any other machine I try, isValid() fails. The file exists in the correct place (current directory), I've checked a hundred times. Any clue as to what could cause a gif not to load?
