Thanks for the reply.  Yes I saw this but I don't think it's the case. 
I do have some remote debugging set up but not for this project.  Also, 
it seems to only happen when I'm using Qt 5.3.  I've been using 4.8 for 
several Linux projects both with and without remote debugging but 
haven't seen this issue.  Unfortunately for this project I'm using 
QtSerialPort so I can't build it in Qt 4.
