does it give that error always - e.g. even on a simple report?
if so, almost certainly is an installation issue and best to report on the oracle forum.
if is only on a certain report, then still the software should handle it better, but probably is something in your sql... fyi - sql queries get parsed to create structures, these are given to calls in the underlying db client runtime. these structures are bound to data variables as specified in your sql. would be somewhere in the software for that where it goes wrong. if you can isolate the sql that causes it you'd stand a better chance of getting help from an oracle support forum.
hope that helps.
