Well for starters you are not checking if the file actually gets opened 
successfully. The QFile::open() function returns a bool for a reason! You may 
not have permissions to create this file for example.

Secondly since you are using a QTextStream on the file I recommend you also 
pass in the QIODevice::Text flag.

See how you get one from here.
