Application: kmix (4)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

1. Deleting files in Dolphin file browser.

2. Before the failure of Kmix was reported, e-mail was being moved between folders in Kmail.

3. The following error message was reported whenever the mouse was clicked on a directory in "Local Folders":

3.1. "Local Folders
Local Folders: Maildir "for collection" is invalid.".

4. Please note that the directory "for collection" does not exist under Local Folders in Kmail. Such a directory was NOT created by the user anywhere in the system.

-- Backtrace:
