RE: FileAppender's OpenFile() has mandatory call to Directory.CreateDirectory(...)

This is a bug in the FileAppender. It has been fixed in the CVS
repository. You can either make a local mod to your copy of the source
or pull the CVS version of log4net and use that.

The fix is to add an Directory.Exists check around the
Directory.CreateDirectory.
