           Summary: KMail2 4.7's "Find messages ..." reproducibly fails to
                    search: "Unknown error. (Unable to create persistent
                    search)"
           Product: kmail2
           Version: 4.7
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: dt85767 at nospammail.net


Version:           4.7 (using KDE 4.7.0) 
OS:                Linux

KMail2's v4.7.0, @ "Find messages ..." always fails, returning error: "Sorry -
Kontact. Can not get search result. Unknown error. (Unable to create persistent
search)"


Reproducible: Always

Steps to Reproduce:
I have multiple IMAP accounts subscribed in KMail.

In v4.4.1x, Search ("Find Messages ...") in a given folder, and/or its
subfolders worked perfectly.

In v4.7.0, @ "Find messages ..." on any account's parent-/sub-folders, the Find
Messages dialog opens, as expected.

But, any/all search attempts result only in a dialog:

"Sorry - Kontact
 Can not get search result. Unknown error. (Unable to create persistent
search)"

No crash.  Nothing further in logs.

Search on these IMAP accounts still works from all other clients, as well as
KDE 4.4.1x's kmail.


Expected Results:  
Search should work.
