#694 Null pointer exception writing days of week
I get this from time to time from my instance of davmail. I had seen the null pointers prior to v5, but didn't have a stack trace. Now the stack traces are showing up, so it's likely that they can be fixed.

Indeed, fixed in trunk... would like to see the BYDAY value though
=> you should see a warn statement
I'm running 5.0.0-2801-1 on Ubuntu Linux. I only see the stack trace, no warn statement near it in the logs.
Sometimes I have this exception above it.
