Fixing FFprobe data
Some of the ffprobe-data contain errors. The following bash magic fixes the errors we've encountered so far:
xmllint is used to find faulty files (line 1), and the files typically have two types of errors: Files containing line-feeds (^L) (line 2) and files missing the ffprobe:ffprobe-end-tag (line 3). Line 4 is equivalent to line 1, and should result in an empty file. If broken-files-remaining is non-empty, somebody should probably have a look at the offending files.
