Description Mickey Stein 2005-06-17 00:00:32 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4

Description of problem:
Since kde 3.4* hit rawhide, I've had some unusual behavour when exiting kde to the  shell. (I stay in init 3 normally and start kde via 'startx'). 

Until the last update to qt (noted version above), I would intermittently see the panel appear for about 3-4 seconds before the usual exit to the shell. If this happened I'd see a message like this:


DCOPClient::attachInternal. Attach failed Could not open netw
ork socket
DCOPClient::attachInternal. Attach failed Could not open network socket
kicker: Fatal IO error: client killed
ICE default IO error handler doing an exit(), pid = 26026, errno = 32


But most of the time it worked without the error and normally exited. 

I tried to move ~/.kde(settings) away but the problem persisted with a clean slate. 

After the recent (yesterday or the day before (13-16 Jun) qt update on rawhide, I now get a repeatable segfault kicker crash 'dialog' box which asks me if I want to save it before exiting. 

This is what I've gotten from it thus far:

I know that isn't very good information but I haven't been able to dig up the qt-debuginfo-3.3.4-15 file (oops ! Never mind, I just found it in .. 'debug' folder on the fedora site ;) ) 

I'll see if I can produce a better crash log and report back with that. 


Version-Release number of selected component (if applicable):
kdebase-3.4.1-0 &  qt-3.3.4-15

How reproducible:

Steps to Reproduce:
1. Start kde from init level 3 via 'startx'.
2. Do anything or nothing in kde
3. Exit kde. 
4. Look for segfault info box.

Actual Results:  I get a crashdump in a kde box. 

Expected Results:  I expect it to exit to a fullscreen shell as normal. It does this after I close the crash info box. 

Additional info:

I'm using 'todays' kernel (2.6.12-rc6-git8) and all other software is up-to-date from rawhide.

Comment 1 Mickey Stein 2005-06-18 06:03:27 UTC
This was probably a bad choice of where to file the bug. I moved it upstream to and found a couple of identical already filed reports. 104152 is
closest, and this is 'supposed' to be fixed in the next release of kdebase (3.4.2).

I'll close this out here.
