segmentation fault

Since on month I'm looking for a problem on bro
when I test it with a nestea attack it make a segmentation fault it
seems that the problem comes from the file in the
ListVal * NetSessions::BuildConnKey(uint32 src_addr, uint32 dst_addr,
uint32 src_port, uint32 dst_port) member fonction the second line :
key = new ListVal(TYPE_ANY);
it seems to be the TYPE_ANY that make problem if I replace it by
TYPE_NET (for example) I have a scan line ...: internal error :
heterogeneous list in ListVal::Append
if someone can help me find the error
Thank's in advance
