Comment 5 for bug 113261

Still doing in rev 12.

If it can help, the new status check icon remains displayed for the accounts which are stuck and not checked anymore.

Here's the log:

checking gmail account 1
checking imap account 2
connecting to the imap server ...
checking imap account 3
connecting to the imap server ...
checking imap account 4
connecting to the imap server ...
... connection done
authenticate user ...
...auth done
getting mails...
...done
...done
... connection done
authenticate user ...
...auth done
getting mails...
...done
... connection done
authenticate user ...
...auth done
getting mails...
...done

At this point, the three IMAP accounts seem to have completed the check process, but their "checkng icons" are still displayed in the GUI. The GMAIL account instead behaves correctly.
After the refresh timeout I get:

checking gmail account 1 ...
...done

Only gmail is checked.
