Finally managed to make some tests removing components from the play.
Disabling IPSEC did not remove the problem. Only removing the NAT
mapping from fxp1 (where the 10/8 and 192.168/16 addresses used for
the ex0@A and IPSEC transport were mapped to fxp1@GW address) caused
the problem disappeared. So, this is yet another ipfilter 4.1 issue.
Of course, it may be due to interaction with the rest of the setup here...
