Mark 1:41 - Why Jesus was angry in codex D

The Textus Receptus reads for Mark 1:41:

ο δε ιησους σπλαγχνισθεις εκτεινας την χειρα ηψατο αυτου και λεγει αυτω θελω καθαρισθητι

'And Jesus having compassion on him, stretched forth his hand; and touching him, saith to him: "I will. Be thou made clean." (Mk 1:41)

The UBS2 text notes the following variant:

ο δε ιησους οργισθεις εκτεινας την χειρα αυτου ηψατο και λεγει αυτω θελω καθαρισθητι
'And Jesus being angry at him, stretched forth his hand; and touching him, saith to him: "I will. Be thou made clean." (Mk 1:41)

The support is:  D it-a,d,ff2,r1, Ephraem (it-b omits word).

Of course even with this flimsy attestation, the reading creeps into many modern versions due to "overwhelming" internal evidence (a conjectured 'harder reading' using the criterion of embarrassment).

Now however, new evidence has come to light, in part suggested by the strange Old Latin support.   It is found in the previous verse, (Mk 1:40), where the text begins,

και ερχεται προς αυτον λεπρος ...

 And there came a leper to him,... (Mk 1:40)

In several ancient Irish MSS we find the Old Latin/Clementine vulgate reading:

Et venit ad eum leprosus deprecans eum : 

However with the following twist:

Et venit ad eum leprecans eum : 

That is, there was a homoeoteleuton error as follows:

Et venit ad 
   eum lepr
 osus  depr

 ecans eum : 

 
dropping 8 letters of text and causing a new word to form: leprecans.  
This is a common spelling of the Old Irish word,

leprechaun

c.1600, from Ir. lupracan, metathesis from O.Ir. luchorpan lit. "a very small body," from lu "little" + corpan, dim. of corp "body," from L. corpus "body"

Apparently the early scribe then,  reading:

Jesus autem misertus ejus..., in the sense of "deplore" back-translated / corrected the Greek in Bezae to read:

  οργισθεις  i.e., Jesus "was angry with" or "despised" the Leprechaun, presumably for being mischievous and duplicious.
