poky-824cc754267ef70b5b46d57f5f28bb390c04c6d2.tar.bz2 correctly handle empty output
If the output from is empty, output.split('\n') would result in a list containing one element which is an empty string while iterating over each line in the output. An exception is then thrown by the line: pkg, pkg_file, pkg_arch = line.split() with the message: Exception: ValueError: need more than 0 values to unpack To avoid this, we add a condition to only split the output if it isn't empty.
