Query with inner join results in error when exported as CSV

[coljac]

A certain query executes fine from within easyaccess but results in an error when redirected to a csv file.

Example:

DESSCI ~> select * from Y3A1_COADD_OBJECT_SUMMARY A INNER JOIN PROJECT2_NEW2 B ON A.COADD_OBJECT_ID = B.COADD_OBJECT_ID where ROWNUM < 4; > all.csv

Fetching data and saving it to all.csv ...

    |             ☆|  Ctrl-C to abort;  Rows : 3, Rows/sec: 0   
<class 'AttributeError'>                        
'DataFrame' object has no attribute 'dtype'   

Nothing is written to the specified file.
The query returns without error if the redirect is omitted.
