After PA shell crash, booting takes a long time

[David Talmage]

I need help figuring this out.  My PA3 WeTab now takes 15 minutes to boot to a 
usable state.  Even then, it's not as responive as it used to be.  PA3 was 
working well until the shell crashed a few days ago.  That was right after I 
installed the okular update.  I don't have reason to suspect okular.

It takes seven minutes to ask me for the kdewallet password.  Eight minutes 
after than, I can pull down the app menu bar.

What can I do to debug this?  Should I forget about it and reinstall PA3?

When PA3 is finally up, wlan0 isn't up.  Eventually, the little wifi icon in the 
status bar responds to my press. Then it takes a minute or two to display the 
wireless settings dialog.  My network is known but apparently its password is 
not remembered.  The soft keyboard doesn't appear when I press the password 
type-in field. Deleting and re-creating the connection to my home network 
didn't change this.

Sometimes I get the crash dialog for kdeinit4.

The power button no longer engages the sleep/shutdown screen.
