I can confirm, the bug affects multiple users. I am using gprename on Ubuntu 13.04.

Steps to reproduce the bug:

1. Plug in a USB drive, go into any directory wihin the USB drive.
2. Open a terminal window in the directory.
3. Launch the gprename from the terminal.

And it will throw the errors mentioned by the user above named "fossfreedom (fossfreedom) "...
