Just wanted to let you all know a quick way to generate a QR code for your bitcoin address is by going to:
Not sure if this will help, however you can goto
http://portableapps.com/apps/utilities/zint_barcode_studio_portable and download a portable app called Zint to make barcodes.
Zint does work on Linux (through Wine).
Zint is what I used to create the QR code that I used as my picture (located to the left).
