If you are targeting the .NET Framework 3.5, the most elegant solution would be an extension method in my opinion.

public static class ObjectExtensions
{
    public static string NullSafeToString(this object obj)
    {
        return obj != null ? obj.ToString() : String.Empty;
    }
}

Then to use:

attribs.something = entry.Properties["something"].Value.NullSafeToString();
