Maybe you should add a check for if the codec could be found.
In MainWindow::load():

QTextCodec *codec = QTextCodec::codecForName(codecName);
if (codec) {
	QString str = codec->toUnicode(data);
	ui.textEdit->setPlainText(str);
}

QTextCodec *codec = QTextCodec::codecForName(codecName);
if (codec) {
	QString str = codec->toUnicode(data);
	ui.textEdit->setPlainText(str);
}

To copy to clipboard, switch view to plain text mode 

As docs say:
QTextCodec::codecForName() returns 0 if no codec matching the name name could be found.

So I'd suspect the usage of null pointer.. Probably the "other" machine does not have the codec installed?
