Subject header is as follows. ( [CRLF]==0x0D0A, [HTAB]==0x09 )
> Subject: A(z) "FlashFXP" =?UTF-8?B?dGVybelr?=[CRLF]
>  =?UTF-8?B?IG1lZ3JlbmRlbOlz6XZlbA==?=[HTAB] kapcsolatos =?UTF-8?B?bWVnamVneXrpc2Vr?=[CRLF]
Same problem as Bug 271312.
 Bug 271312 : [HTAB] as white space char for header folding
 This bug   : [HTAB] at mid of mail subject data(just after a UTF-8 encoded atom)

Why mail sender puts [HTAB] in mail subject?
Mail sender expects extra spaces/indention at [HTAB] position like program source viewing?
