It's possible that one of your mailboxes has a name that after removing all
characters that should not be in table names becomes an empty string.
imap.py does this
# remove unwanted characters and store original names
# Don't allow leading non alphabetic characters
mailbox_name = re.sub('^[_0-9]*', '', re.sub('[^_\w]','',re.sub('[/ ]','_',
mailbox)))
Later in define_tables IMAPAdapter uses the names of the mailboxes to
create a table for each one of them. I don't really know why this was
decided instead of just using a single table with a Field mailbox.
If this is indeed the problem, this can be circumvented by passing the
mailbox_names argument to the IMAPAdapter define_tables call, this is a
dictionary where you give table names for each mailbox. It's of the form
{tablename: mailboxname}.
That said you also found a bug in web2py because:
if (not isinstance(tablename, str) or tablename[0] == '_'
Should be
if (not isinstance(tablename, str) or (not len(tablename)) or tablename[0]
== '_'
