           Summary: KMail extremely slow after using search tool
           Product: kmail
           Version: 1.12.4
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: search
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: linux at daniel-bauer.com


Version:           1.12.4 (using KDE 4.3.5) 
OS:                Linux

After using the search tool for a search in all my my approx. 50 folders with
approx. 5000 mails, KMail gets extremely slow, allthough I deleted the folder
with the search results.

It seems to me that KMail remembers and performs the search in the background
each time I restart it. It uses a lot of CPU-Power, it is almost impossible to
change to another folder, after clicking on a mail to see the preview it takes
about 30 seconds until the previev appears. Everything is slow.

After using the search tool again, but in a small folder with only 20 mails and
searching on one criteria only, KMail behaves normal again.


Reproducible: Always

Steps to Reproduce:
- search for 2 criterias in all folders and subfolders with a lot of emails:
KMail gets slow (also after deleting search result folder, user logout/login,
reboot.
- perform small search (small folder, only 1 criteria): KMail returns to normal
behaviour.
