In MediaMonitorUnix::AddDevice? in libs/libmyth/mediamonitor-unix.cpp there is a check to make sure that the fstab struct pointer it was handed is not null. But the check comes after the pointer was dereferenced.

(In [16208]) Fixes #4744. Moves a null pointer check to a slightly earlier point in MediaMonitorUnix::AddDevice?() so we don't try to dereference it before NULL check (looks like it was moved to a bad location for a now commented out debug statement..)
