Bug 304391

Application: kontact (4.8.3)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.2
Operating System: Linux 3.3.8-gentoo x86_64
Distribution: "Gentoo Base System release 2.1"

-- Information about the crash:
- What I was doing when the application crashed:
Before the application crashed, I had moved all (about 1000) messages from one IMAP folder to another IMAP folder on the same server. (Online, but it took a while.) When the source folder was shown in KMail as empty, I tried to unsubscribe from that IMAP folder, so I opened the "Manage folder subscriptions" window. But there, nothing at all was marked as subscribed, even for other IMAP accounts and local accounts. So I closed that window and then I closed KMail. That's when I got the crash report. (Or maybe I got the crash report when I tried to restart KMail; I am not sure what happened first.)

- Unusual behavior I noticed:

The icons for the IMAP accounts in the Manage folder subscriptions were wrong. They looked like the icon for local Maildir accounts.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
