No it is not an issue I have ever come across on dequeue. The only time I could imagine this happening is on enqueue if the MSGID is not unique. Only on AIX have i seen an issue related to ORA-1 on enqueue.
On dequeue your msgid has already been created and you are effectively just selecting out the message.
The only way I could you progressing this would be to set an errorstack on ORA-1 but that would be more trouble than it is worth unless you can be reasonably sure you can reproduce the issue within a small timeframe otherwise you will get lots of tracefiles for perfectly legitimate ORA-1 errors.
