I use the Q&A module on my site and it works perfectly - except for one user.  When he tries it gives a "A critical error has occurred. An unexpected error has occurred" message.  The event log gives me:

Initially I though his display name [xxxxxx Quiñones], may have been a problem due to the accented characters.  I did try removing the accented characters, but it did not help.   I tried creating a test character with accented characters in the display name (normal in the user name) and it also gave the same error.

Journal_DeleteByKey seem to return multiple records per key, please check your database.

ok, after further investigation:
stored procedure Journal_DeleteByKey tries to identify a single journal entry by its ObjectKey. unfortunately, there is no unique key on this field in journal table and any delete call fails, if there are more than one items using the same object key,
You may identify the duplicate entries by running the following statement from Host > SQL:
SELECT JournalId FROM {databaseOwner}[{objectQualifier}Journal] WHERE ObjectKey IN (SELECT ObjectKey FROM {databaseOwner}[{objectQualifier}Journal] GROUP BY ObjectKey HAVING Count(1) > 1)
