I've seen that, too. No idea so far what causes it. If it's not some stupid bug in akregator, it might be caused by the metakit update a while back. Let me know when I see similar metakit-related crashes which don't have "setStatus' in the backtrace, e.g. when fetching feeds.

Would be good if this was fixed before KDE 4.3 release. At the moment Akregator I can not use Akregator because of this bug.
I have spent some time to try to make this bug reproducable so that I can relate it to the feed which crashes. I turned of autofetch of articles and fetched every feed one by one, waited for each feed until it was done. No I have found the evildoer. And the big surprise: It is the planetkde himself. http://planetkde.org/rss20.xml I do not know if is the feed as such, since you mentioned the metakit storage: The folder contains 3556 articles and that is funny 1245 unread articles. Normaly I only have a few unread articles. That must be caused by the bug.
Just to be on the safe side. Here is the exact crash report caused by this crash.

So now I can narrow it down to a feed. The question is, can I help further? Is it possible to extract this folder from the database and send it to you.
The feed is stored in $KDEHOME/share/apps/akregator/Archive/$MANGLEDFEEDURL.mk4, where MANGLEDFEEDURL is the feed's URL with some special characters replaced by _. If you remove that file (and possible other corrupted files), Akregator should start up again. It seems this is a duplicate of infamous Bug 116482. The problem is known - metakit reads the size of some entry from the file and then allocate the memory. As the mk4 file is corrupted, the size read is a random number - usually far too big. The OS then either prevents the allocation (crash), or, if it is big but below the limits of the OS, it hogs tons of memory first and then crash (reading the next field, I guess). We haven't found a way to fix it, but hope to have Akregator ported to Akonadi for 4.4, and get rid of metakit.
I tried it and you are correct. No crashes anymore with this. Only a shame I lost my planetkde-archive :-(
