What I meant was the actual FBSQLException (and its stacktrace) that
makes QueryDataSet throw this exception. It could be that it isn't kept
as the cause (ie getCause()) of that DataSetException though, which
would be unfortunate, as it makes pinpointing where in Jaybird this
occurs so much harder.

I know I have seen this message before on this mailinglist, but I can't
say if there was an actual cause identified.

How about upgrading one or more installations that recently had this
error (or those sites that have this most frequently)?
