On linux SndFileSource::get_soundfile_info was being called with an empty path value when clicking on a folder in the left side part of the file browser which resulted in an unnecessary error message. On Windows every time a directory was selected in the Import dialog, SndFileSource::get_soundfile_info would fail to open the directory in read only mode and produce an error, but as we don't want to query/open soundfile info for directories anyway just test and return if the path is a directory.
