           Summary: KMail sometimes shows only a spinning wheel for a
                    folder, no contents
           Product: kmail2
           Version: Git (master)
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: folders
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: thiago at kde.org


Version:           Git (master) (using Devel) 
OS:                Linux

Sometimes, after starting, KMail shows one or more folders with the "spinning
wheel" indication that it's working. While it's normal for it to do that for
large folders that haven't been used in a while, this happens on start up and
does not go away for some folders.

Often, in this situation KMail displays an error dialog saying
  Unknown error. (Unable to fetch item from backend)

I am unable to read any emails that were present in the folder when KMail
started. Newly arrived emails show up, though.

To make this problem go away, I need to completely stop both KMail and Akonadi
and it takes a few tries. I *think* it's associated with a background job that
is still running but has no visible UI indication. That might explain why
stopping Akonadi causes it.

Reproducible: Didn't try

Steps to Reproduce:
1) start KMail
2) close KMail, don't stop akonadi
3) start KMail again

Actual Results:  
Some folders (especially the root INBOX folder on my IMAP server) are not
usable at all, even if I wait a long time.

Expected Results:  
All folders should be usable after a reasonable settle-down time.
