Of course not. If charon does not have a valid route, it should defer
any MOBIKE update:

> disappeared from eth0
> no route found to reach, MOBIKE update deferred

If a usable address and a valid route appears, it should update the
tunnel using MOBIKE:

> appeared on eth0
> requesting address change using MOBIKE
> generating INFORMATIONAL request 8 [ N(ADD_4_ADDR) N(ADD_4_ADDR) ]
> sending packet: from[4500] to[4500]

Please try to attach a debugger (ipsec start --attach-gdb), a backtrace
of the crash would help.
