www/urlwatch breaks at runtime

[Sebastien Marie]

Hi,

After an update of packages (pkg_add -u) urlwatch breaks at runtime with
the following exception:

$ urlwatch                   
Traceback (most recent call last):         
  File "/usr/local/bin/urlwatch", line 101, in <module>          
    urlwatch_command.run()            
  File "/usr/local/lib/python3.6/site-packages/urlwatch/command.py", line 167, 
in run
    self.urlwatcher.close()
  File "/usr/local/lib/python3.6/site-packages/urlwatch/main.py", line 97, in 
close
    self.cache_storage.close()
  File "/usr/local/lib/python3.6/site-packages/urlwatch/storage.py", line 465, 
in close
    self.db.close()
  File "/usr/local/lib/python3.6/site-packages/minidb.py", line 170, in close
    self._execute('VACUUM')
  File "/usr/local/lib/python3.6/site-packages/minidb.py", line 153, in _execute
    return self.db.execute(sql)
sqlite3.OperationalError: cannot VACUUM from within a transaction

Does the switch of MODPY_DEFAULT_VERSION_3 from 3.4 to 3.6 changed
something related to sqlite3 ?

My host is amd64 with -current. (note that some parts of the port tree aren't
updated due to libssl version changes : my system base isn't up-to-date
regarding latest libssl&co bumps).

Thanks.
