Bug 164265

Confirming the bug, and also when akregator crashes it looks like the shortcuts like ALT+F2 don't seem to work. When trying to go to system settings and selecting keyboard shortcuts I get "Failed to contact the KDE global shortcuts daemon
Message: The name org.kde.kded was not provided by any .service files
Error: org.freedesktop.DBus.Error.ServiceUnknown".

Sanitize findByURL. This stops leaking empty QLists using operator[] and and maybe also fixes the crash in 164265

Using KDE 4.1 RC1 I get a similar crash when akregator starts:

Well Akregator seems to work just fine in RC1, installed from Kubuntu binary packages. The problem remains in trunk.

Thanks for the feedback, Matej. It seems that akregatorrc was the cause of the crash here. It works fine now.

Is bug http://bugs.kde.org/show_bug.cgi?id=116482 not related?

> Is bug http://bugs.kde.org/show_bug.cgi?id=116482 not related?

No it's another issue.

I'm not sure if this is really the same as #166569...however, I can dump my feeds.opml and archive contents somewhere if it'll help.

after clean settings in ./kde folder everything is ok 

Update related to my report (#166569, which was apparently marked as a duplicate of this one) - I completely deleted the .kde/share/apps/akregator directory and the .kde/share/config/akregator* files.  I opened a akregator.  I deleted the "KDE" default feeds.  I added a single feed ( http://www.twis.org/audio/podcast.rss , though I suspect the feed's not at fault here ).  I configure the feed to check every 5 days, and limit to 20 articles.  I exit.  I attempt to restart akregator: segfault again.

I've tried it without deleting the KDE default feeds as well - same results.

AMD64, gcc 4.3.1, KDE 4.1.0 release source complied from Gentoo's KDE4 overlay.

(One additional followup - the same set of files opens fine, repeatedly, with my old parallel install of Akregator from KDE 3.5.9, so I'm guessing it's not a magically repeatedly-"corrupted" file problem.)

I tried that, cleaning akregator related files from ~/.kde4 (commetn #13), but it does not work for me using KDE 4.1.0, Akregator 1.2.50. Could one set this bug back to new?

And another followup, I can confirm this is still a problem in 4.1.1...
Anything I can supply from this end that might help solve this one?  Akregator and k3b are the only two KDE 3.5.x applications remaining that make me keep the 3.5.x install in parallel on my machine here.

Used System is Kubuntu 8.04 with KDE 4.1.1
here is a paste of the Crashmanager 
http://paste.ubuntu.com/44547/

I also confirm the behavior. I use  Kubuntu 8.04 with KDE 4.1.1. You find the  paste of the Crashmanager at http://paste.ubuntu.com/48882/

Same here.
If I remove ~/.kde4/share/apps/akregator/Archive/* Akregator starts again. But if i pull the feeds, quit akregator and try to start it again, it crashes with the following dump http://paste.ubuntu.com/50747/

Hope that helps and I can soon start to use the KDE4 PIM-Suite.

The things are really even worse: akregator not only crashes itself but the whole kontact.

Ok, I removed and readded all of my feeds and found the one that seems to make problems: Its the RSS Feed of sueddeutsche.de found under
http://www.sueddeutsche.de/app/service/rss/alles/rss.xml
If this feed is removed from feeds.opml akregator starts without problems, if I add it again, close akregator und start it again, the problem returns.
Why is this feed causing so much trouble?

I can confirm this bug.
It happens on my Debian machine (lenny) using kde 4.1.2 and on my gentoo machine using the same 4.1.2.
On the first start it works fine... after deleting the default feeds and adding my standard feeds, it crashes and won't start again.
The used feeds are the following:
- lwn.net
- phoronix.com
- heise.de
- planetkde.org

Architecture, both amd64.

I can confirm this bug on OpenSUSE 11.0, Version 1.3.1, Using KDE 4.1.2 (KDE 4.1.2) "release 44.5".  This bug occurs when you limit the number of article stored in the archive.  Changing the archiveMode in the feeds.opml file in .kde4/share/apps/akregator/data to globalDefault makes akregator start normally again.

I am not able to confirm this workaround. It does not work for me on KDE 4.1.2 (Kubuntu 8.04 w/ ppa repos). removing ./.kde4/share/apps/akregator/Archive/* is still needed here to make akregator start again.

Still crashes for me in trunk.
I removed [Archive] section from akregatorrc (and tried to remove that whole file too - didn't help). 
Also I removed all maxArticleCount entries from feeds.opml. Didn't help too.

Crashes are happening at startup and 100% reproducible.

Here's the backtrace:
