As a new user of GNU radio with a couple RTL2832 dongles to play with I
used the build-gnuradio script to install on Fedora 16 and Ubuntu
12.04. The Fedora install worked fine; but the Ubuntu one produced this:

Segmentation fault (core dumped)
The traceback showed the fault to occur in libusb1, and seemed similar

I noticed this patch at the head of master touched the same general part
of the code.

Reverting this change fixed the issue.
