ORA-1555 on data dictionary query

A developer came to me with an error message the other day--(Oracle
11gR2 on Solaris)
ORA-01555: snapshot too old: rollback segment number 16 with name
"_SYSSMU16_3927122202$" too small
The error was recorded in Grid Control, with the ID of the SQL that
caused it. To my surprise it was a query on ALL_IND_PARTITIONS. I
would have expected a query on the data dictionary to look for
consistent-read blocks in the SYSTEM tablespace, as create/drop/alter
index DDL would create undo there. Am I wrong? Has this changed in
11g?
TIA!
