kontact (4.10.2) on KDE Platform 4.10.2 using Qt 4.8.4

- What I was doing when the application crashed:

Exiting Kontact.

Yet another backtrace from my always-crashing-on-exit experience of Kontact. :-(

kontact (4.10.2) on KDE Platform 4.10.2 using Qt 4.8.4

- What I was doing when the application crashed:
I noticed that one of my accounts disappeared from the accounts and favorites panes in Kontact. I then quit, which is when the crash occurred.

- Unusual behavior I noticed:
My accounts disappeared and my ownCloud folder appeared in the accounts pane, which isn't usually there.
