Yes, I found it. 

(There has been a second core, this afternoon and I started working on
this beta bug...)

The fault condition happen when:

Player A in allied with Player B
Player B unit is in Player A city Example
Player B is not allied with Player C
Player A meet Player C and agree to transfer city Example to Player C

Tomorrow I will work on a patch for this.

(I have uploaded a savegame in incoming, named notallied.sav.gz, you
need to connect as all three players, pagnin, pagnin2, pagnin3, and
transfer Indian city Kanpur (which contains isreali horseman) to
Lithuanian, after agreed on this transfer press turn done, and ...
BOOM!!!)
