Comment 1 Rex Dieter 2010-05-25 21:24:23 UTC 
When it crashes, you should get a backtrace.  Please post that.
Comment 2 Karsten Roch 2010-05-25 23:09:45 UTC 
There is no backtrace... When starting the program from console, it simply closes, the last few lines in console are shown above. Also, abrt did not catch anything. 

I only see this at /var/log/messages/

May 25 23:02:46 krakatoa kernel: Process 3157(k3b) has RLIMIT_CORE set to 0
May 25 23:02:46 krakatoa kernel: Aborting core

Comment 3 Michał Małek 2010-06-07 21:18:39 UTC 
Don't you get this nice KDE crash window? There is a backtraca on the second tab. Without backtrace it'll be hard to do something about this bug. I'm setting NEEDSINFO->BACKTRACE status for now.
Comment 4 Karsten Roch 2010-06-07 23:03:51 UTC 
Sorry, but i don't get the KDE-crash window. The program simply closes down. 
Also abrt did not catch the error. 

/var/log/messages/   shows:

Jun  7 22:52:34 krakatoa kernel: Process 4085(k3b) has RLIMIT_CORE set to 0
Jun  7 22:52:34 krakatoa kernel: Aborting core


I run "gdb /usr/bin/k3b", but I don't see any different result. The gdb-logfile is posted here:

Comment 5 Michał Małek 2010-06-08 22:00:55 UTC 
Try this:
1. Run k3b
2. Open terminal and run:
> gdb /usr/bin/k3b `pidof k3b`
3. In GDB console type "continue"
4. Reproduce crash in k3b
5. Get backtrace in GDB console by typing "bt"
6. Paste backtrace here :)

If you'll still have some issues go to #k3b channel on Freenode and catch me there (mmalek). We'll try to work this out together.
Comment 6 Karsten Roch 2010-06-09 21:57:13 UTC 
I tried 3 times, it always crashes, each time the Headline of the error looks a little bit different.
Here are 2 Backtraces from gdb:

TIA

Comment 7 Michał Małek 2010-06-09 22:22:22 UTC 
Great, now we can see it's kdelibs issue. I'm redirecting this report to kdelibs guys. Thanks!

*** Bug 242398 has been marked as a duplicate of this bug. ***
Comment 9 Paulo Dias 2010-06-30 23:52:52 UTC 
Any kde dev took a look at this, it still crashes with k3b 2.0.0 and kde 4.5 rc1, hope this is get caught before final.
Comment 10 Karsten Roch 2010-07-08 21:22:14 UTC 
I updated today to 

Qt: 4.7.0
KDE Development Platform: 4.4.92 (KDE 4.4.92 (KDE 4.5 RC2))
K3b: 2.0.0
kernel 2.6.35-0.29.rc4.git0.fc14.i686

no changes, it crashes in the same way like before.

Comment 11 Christoph Feck 2010-07-09 01:25:35 UTC 
Not sure why KCategorizedItemView runs into a recursion, but I have prepared a patch for k3b to work around it.
Comment 12 Christoph Feck 2010-07-09 01:25:54 UTC 
Created attachment 48702 [details]
proposed patch

This works around the kdelibs endless loop bug visible in k3b by adding all plugins per category in one addPlugins call. Please review and apply.
Comment 13 Christoph Feck 2010-07-09 01:31:04 UTC 
Well, looking at my own patch, it could be simplified to not use a QSet, but just use the keys() from the categoryNames hash, but I am too lazy to change it now :)
Comment 14 Michał Małek 2010-07-09 23:16:00 UTC 
@Christoph: thanks for the patch but I will wait with applying it for now. I'd be the better to fix the actual cause of crash, someone may stumble into it in the future.
Comment 15 Paulo Dias 2010-07-15 23:00:59 UTC 
@christoph: hey chris, tks for the patch but it didnt compiled cleanly:

All:
 Sorry, but that is kde 4.5 with k3b 2.0 and not k3b 2.0.1.  That version isn't officially out yet. Only the development version which doesn't work as well.

proposed patch

Updated patch that implements the idea from comment #13.

Qt 4.7.0 RC got released, and more people will use Qt 4.7.0. I suggest to apply the patch until someone (Raphael?) has time to look into the issue.
Comment 30 9bv1tu2a 2010-09-05 04:50:11 UTC 
I have some issues with k3b (250181) so I tried to configure - Guess what?

Click Settings>Configure K3b... - Instantaneous crash
No crash report window
Tried it a few times - same result
Linux Mint KDE 9
K3b 1.91
QT 4.7.0

Purged K3b - reinstalled - same results

I did an update this morning with the Kubuntu backports ppa enabled and I can now open the settings window.

Now I just have to figure out why it can't find normalize-audio.
Comment 33 Tom Chiverton 2010-09-05 14:16:54 UTC 
Aye; there was a 2nd tranche of updates just now, and it's fixed for me.

Me three . . .

A bunch of updates came through Linux Mint KDE 9 (Ubuntu) this morning and my K3b 1.9.1 is now K3b 2.0.1.

I can confirm that Alex' fix for bug 226631 also fixes k3b, so when you update to KDE 4.5.2 you no longer need the k3b patch.

Two remarks: 

a)
I have Opensuse 11.3 (x86_64) running with KDE 4.5.2. However, the problem with K3b still exists. Clicking on settings in K3b leads to a crash of K3b.

OS: Opensuse 11.3 x86_64
KDE: 4.5.2 (RPMs from Opensuse KDE Factory repository)
K3b: 2.0.1 (RPM from Packman 2.0.1-1pm.2.5, however the Problem also occurs for other subversions of 2.0.1) 
Qt: 4.7.0

b) 
To me it seems that bug 232691 is a duplicate of this bug.
Comment 42 Christoph Feck 2010-10-16 15:05:00 UTC 
This isn't a duplicate. Bug 232691 is a problem with policykit, while this one is about the infinite recursion.

Do you get DrKonqi when it crashes?

No, I just klick "settings >> configure k3b" and the k3b window disappears together with a disappearance of the k3b process from the process list.

Comment 44 Unknown 2010-10-16 16:00:03 UTC 
In Bug 253567 there is the full backtrace, but that's generated by gdb not by DrKonqui.

Also in that bug it was mentioned why this bug can occur in KDE 4.5.2 on openSUSE (version mismatch).
Comment 45 Christoph Feck 2010-10-16 16:11:02 UTC 
In other words, you have confirmed that openSUSE ships a pre-tag 4.5.2? I got no answer for my comment at bug 253567.

No, I haven't asked that yet. But I'm unsure where can I do. openSUSE shipped more updates after releasing the first 4.5.2 packages, but I don't know whether they are just repacking or containing some fixes.

Could you provide an e-mail address, I will write them, but I don't know where to start.
Comment 48 Terry 2010-11-14 06:05:12 UTC 
I have installed a new version of the operating system (PCLinuxOS-kde.10.2010) and this bug is no longer present.  K3b version is 2.0.1, KDE 4.5.3
Comment 49 Ralph Moenchmeyer 2010-12-03 14:54:47 UTC 
Tested again for Opensuse 11.3 (x86_64), KDE 4.6 beta (from Opensuse's Factory Repository), Qt 4.7.1. 

With the latest RPM 2.0.1-44.1 for K3b in the Factory Repo K3b obviously is working again under Opensuse 11.3 - at least under KDE 4.6 beta. 

No crash any or disappearance of K3b any more when opening the settings dialog.

I applied this patch on k3b-2.0.1_4
KDE 4.5.4
qt4 4.7.1
FreeBSD 8.2-PRERELEASE
and k3b settings really work now

Thanks for the patch
