Unless you're actively using an app that uses mediascanner2, it might be best to just remove the package. This package was developed for the Ubuntu Phone project, which is no longer based on Trusty.
The latest version almost certainly improves matters (it better protects against crashes caused by the codecs), but I don't know whether we'll be back porting it to 14.04 (all current development is targeting Xenial and Vivid).
