Bug Description

<facundobatista> there's the notification error, but the problem is that LocalRescan is breaking itself by entering invalid paths into SD
<rye> facundobatista, so, if LR hadn't placed that filename to sd then notification would not have broken the SYS_CONNECT_MADE (in the 822226 report), am I correct?
<facundobatista> rye, yes, but most important, LR would be continued ok

The one that should check if the path is valid is LocalRescan.

It can't be done in the signals processors (that are close to real validation, in the freeze_commit stage).

The reason for this is that if LR finds an invalid path it needs to ignore it; in files there is no problem, but for directories it shouldn't scan that directory later.
