IP communications no longer work after IOS Upgrade

After an unhappy upgrade from 12.4(15)T7 to 12.4(22)T, my point-to-point GRE Tunnels over IPSec no longer work... I'm explaining, CDP packets are OK, but no IP or ICMP packets can reach the hub when coming from a spoke.

With a debug ip packets (on the spoke), I can see that from the Hub, ICMP packets come to the spoke, but the return never arrive to the Hub...

Everything was working so good in 12.4(15)Tx, except a little WebVPN problem.

Thanks for your help,
