IOException not being caught if java process does not have permission to save attachment

If, for some reason, the java process running Confluence fails on the creation of an attachment handle the IOException gracefully.

The user reporting this had the following stacktrace in their log but the 500 page contained a slightly different error message (see second stacktrace).

Note - this is after the attachment upload but during the save to a specific directory in conf. home.
