Bug 284835

Application: kded4 ($Id$)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: From sleep, I reopened the laptop and the wireless would not re-initialize. It wanted the wifi password, which should have been saved, I reentered this information and was stuck on "configuring interface". I restarted the machine and upon logging in, while the wifi was initializing, KDE Wallet came and asked me for the master password. I entered the password and KDE wallet crashed. The wifi still connects. Then after 5 minutes or so of being logged in I get a series of error messages (not task specific) that says "Nepomuk Indexing Agents Have Been Disabled".

The crash can be reproduced some of the time.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
