Hi! I tested starting ser with all common and ser's modules - in arbitrary order. Of course this failed, nevertheless ser should not crash: root@flunder:/# ser loading modules under /usr/local/lib/ser/modules:/usr/local/lib/ser/modules_s ERROR: bad config file (29 errors) Segmentation fault (core dumped) backtrace: Core was generated by `ser'. Program terminated with signal 11, Segmentation fault.
