I have an event with attachment on an exchange 2003 server, which is crashing e-calendar-factory with a message as described in openchange tracker [1]. Even it is fixed in openchange it would be better to workaround the issue for older openchange-s too, thus this bug report.

[1] http://tracker.openchange.org/issues/298

The backtrace is:

[Thread 0xb3bfcb70 (LWP 17389) exited]
unhandled conversion case in cast_SPropValue(): 0x1048
e-calendar-factory: libmapi/property.c:732: cast_SPropValue: Assertion `0' failed.

Program received signal SIGABRT, Aborted.
