Due to a minor change in the NetworkScanners/BwAuthority/run_scan.sh the bwauthority cannot be run because the necessary configuration files are removed.

This line:

find data/scanner.* -name .svn -prune -o -type f -a ! -name '*-done-*' -exec rm {} +

introduced in 5ccc8b14ce1269ac93bb5506b010a5f1c6b4a77a will remove all the files from data/scanner.*, which includes the bwauthority.cfg file. When that file is removed, the bwauthority scripts will get into a tight loop and spit python traceback errors in the log for each scanner about:

NoSectionError: No section: 'TorCtl'

that is because the config files don't exist, and because they don't exist, there is no [TorCtl] section in the configs.

The fix is pretty simple:

diff --git a/NetworkScanners/BwAuthority/run_scan.sh b/NetworkScanners/BwAuthority/run_scan.sh
