This happens in 2012.11, I dunno about the older versions.

I noticed this with a few of my packages, but most recently with a custom
kernel tar file url.

For example, I have the following URL in my .config file:

BR2_LINUX_KERNEL_CUSTOM_TARBALL_LOCATION="https://github.com/raspberrypi/linux/archive/rpi-3.6.y.tar.gz"

While make-ing, buildroot adds an extra slash to the URL and tries to download 
"https://github.com/raspberrypi/linux/archive//rpi-3.6.y.tar.gz" instead; this
results in an error (at least if the target server does some redirection
kung-fu like github does).

Example Output:
