evolution+openchange crash



Before filing a bug, I'd like to get another opinion. I'm seeing the following crash in evolution, using openchange with $DAYJOB's exchange server. It's dying in libical, but from the libical portion of the stack trace, exchange-mapi seems to be the problem. However according to gdb, the parameter is fine when passed. Any thoughts? If I file this, should it be against evolution-mapi, or libical?
