Trace analyzer in RAC

Does anyone know how Oracle's trace analyzer should be configured in RAC. It works fine in single instance but spits out the following message when I try to run it in a RAC instance.

exec trca$i.trace_analyzer('racvt1n2_ora_7276.trc'); BEGIN trca$i.trace_analyzer('racvt1n2_ora_7276.trc'); END;

ERROR at line 1:

ORA-00001: unique constraint (TRCANLZR.TRCA$_STAT_PK) violated

ORA-06512: at "TRCANLZR.TRCA$I", line 499

I have tried to completely de-install and then re-installed it but have not had any luck. and Any help will be appreciated. Thanks
