Hi guys, i've opened console to see why Chrome crashes sometimes and i found that error:

04/03/13 13:08:15,040 appleeventsd[51]: 10759711: Error #19 (os/kern) urefs overflow attempting to add send right to port ( port:28931 rcv:0,send:65534,d:0). (addSendRight()/XPCHelpers.cp #428) EntitlementsQ

Every 2 sec! What could create that error?? o.O
