I've tested this change and can confirm that it also fixes issue #580.

I would suggest to check, if there are some parts, otherwise it will return empty parts when it is empty
if ( count($parts) > ($config->get("options.allow_single_parts") ? 0 : 1) ) {

Why not always allow single parts? I think just 'count() == 0' needs to be disregarded.

I implemented a fix here for Issue 582 and related (issues of bodies not being decoded etc) as follows:
Added new config option, "allow_single_parts", bool defaulting to true
Altered Structure::parsePart to alter "fix" commited in issue Fix bug when multipart message getHTMLBody() method returns null #455 to rather be:
if ( count($parts) > 1 || $config->get("options")['allow_single_parts'] ) {This will now always return parts if there are multiple but allows it to optionally also return if only a single part is found.
I believe the default here should be true (always return recursive part even if only one part is found in a multipart block) as this how it operated for years before, and it would seem in most cases looking at all issues raised since this commit was pulled in this is valid behavior (otherwise we get undecoded parts).
For edge cases such as experienced by @michalkortas there is the possiblity of setting "allow_single_parts" to false in thier configuration, thus still achieving what they set out to in the PR but in a way that does not affect most users.
