Application: kwalletd (0.2)
KDE Platform Version: 4.12.97
Qt Version: 4.8.6
Operating System: Linux 3.11.0-19-generic x86_64
Distribution: Ubuntu 13.10

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

Simply waited for the screensaver to start.

kwalletmanager is configured to close the wallet when the screensaver starts. The crash happens only when the wallet is open.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Wallet Service (kwalletd), signal: Aborted
