Evolution (openchange?) crashes with the following:
exchange-mapi-connection.c:1004: Entering exchange_mapi_connection_fetch_items: folder-id E69E0E0100000003 libexchangemapi-Message: exchange-mapi-connection.c:1006: exchange_mapi_connection_fetch_items: lock(connect_lock)
**
camel:ERROR:camel-internet-address.c:535:camel_internet_address_format_address: assertion failed: (addr)
Aborted

I've done some minimal debugging; the 'item' (previous call) has no from name or from address, though it apparently should (does in OWA, for example). I can reproduce this every time trying to sync/view certain folders.

I'm using evolution+openchange against my company's exchange server (very unlikely they'd change anything on their end to help, here).

Fully-updated f11 packages as of 2009-06-19.

I'm willing to assist with further debugging (but cannot give access to any machines/accounts/resources and probably can't even provide sample mails); please let me know what other information is useful.

Anyway, backtrace:
