This is python 2.7 specific, and was introduced between casacore 3.3.0 and the latest master.

Reproduce with:

# Create some test dataset
taql 'select rownr() as somenum limit 10 giving numbers.tab'

> from casacore.tables import table, tablecolumn
> tc = tablecolumn(table('numbers.tab'), 'somenum')
Successful readonly open of default-locked table numbers.tab: 1 columns, 10 rows
> len(tc)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: __len__() should return an int

See this travis build. The python3 build against casacore master succeeds.
