Comment 12 for bug 1224410

Attaching a valgrind trace obtained by running mediascanner with 'valgrind --track-fds=yes --trace-children=yes' and scanning 74 mp3 files; I interrupted the process with CTRL+C a few seconds after it finished scanning. The trace shows 47 open fds referencing cache files, along with stack traces showing where the origins of fds are.
