Comment (by cypherpunks):

 In my case PERSON B is not listed anymore in the contact list, so there
 was no "little down arrow" to click... but i see what you mean with
 contact merging, therefore i had this idea:

 I closed Tor Messenger and opened Pidgin with the same account. There, two
 un-merged accounts were listed, both as "PERSON A", while one of them was
 obviously "PERSON B" as shown in the tooltip.

 So what seems to have happened is that somehow the two got merged and/or
 messed up in Tor Messenger, with one of the two getting the ID of the
 second one... Still they are not technically "merged contacts".

 Can you open Tor Messenger, find that user in contacts menu, click them,
 then you should see a little down arrow appear. Click that and it should
 show the merged accounts. If what I suspect is happening, these contacts
 got accidentally merged. Right-click (context menu) on
 `ioerror at jabber.ccc.de` and choose "Detach from contact".

 handling merged contacts or disable the "feature" altogether.
