Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/gajim/gtk/search_view.py", line 179, in _on_search
    self._add_results()

                 ^^^^^^^^^^
  File "/usr/lib/python3/dist-packages/gajim/gtk/search_view.py", line 389, in __init__
    self._client = app.get_client(account)
                   ^^^^^^^^^^^^^^^^^^^^^^^

    return connections[account]
           ~~~~~~~~~~~^^^^^^^^^
KeyError: 'chat.example.com12'

Additional information

If I run the following code in a plugin:

    accounts = []
    for account in app.settings.get_accounts():
        account_id = app.storage.archive.get_account_id(account)
        accounts.append((account_id, account))

then the result is as follows:

[(1, "chat.example.com"),
 (1, "chat.example.com1"),
 (1, "chat.example.com12")]

i.e. all of the account IDs are the same. If have three accounts defined, but only one is enabled. Where are the duplicate account IDs coming from? And the account names?
