Version: 3.5rc1 (using KDE KDE 3.5.0)
Installed from: SuSE RPMs

Akregator cannot be started for me since I upgraded to RC1.
Beta2 was ok.
starting akregator from the command line, I get the following message:
akregator: ERROR: Communication problem with akregator, it probably crashed.

The crash window does not appear, however, strace output suggests akregator actually crashes.

I see also this line:

*** glibc detected *** malloc(): memory corruption: 0x08393f88 ***
I'll attach the strace output.

Have you upgraded to 3.5.0? Does Akregator work now for you?

Backtrace produced by KDE crash handler

Akregator crashes on startup saying "Communication problem with akregator, it
probably crashed." This problem started when I upgraded to KDE 3.5.0 and also
upgraded akregator with packages obtained from
http://pkg-kde.alioth.debian.org.

It seems that Akregator crashes while accessing the backend corrupt the metakit storage, which causes crashes then at startup.
A workaround is to move ~/.kde/share/apps/akregator/Archive/*mk4 somewhere else. That should make Akregator start again, but all archived articles are lost.You can then copy mk4 files back and test which one causes the crash...

It would be _very_ useful if someone experiencing this crash could zip the files in Archive/ and send them to me (frank.osterfeld at gmail.com) and also his feeds.opml. (If you want to help even more, identify the exact archive file that causes the crash).

SVN commit 513455 by osterfeld:

Lock archive to avoid metakit archive corruption due to multiple write access.
Usually Akregator being a KUniqueApplication avoids multiple Akregator instances accessing the archive, but there seem to
be some cases where KUniqueApp is not safe enough (right after update, multiple KDE sessions, when using --nofork option).
So we lock the archive like KMail does: if locking fails, show an error message to the user, giving him the possibility to
either continue without archive, or to force access.
As this is a severe bug (multiple write access can corrupt archives, which can make Akregator crash at startup), I think
making use of the message unfreeze is justified.

Hi !

I got a problem starting akregator after a machine crash. It's due to a corrupted archive file because moving my archive folder solved the startup issue. But I'm a bit puzzled : how can I identify which mk4 is causing the crash ? It looks like moving some mk4 files out of the Archive folder is making Akregator hang (not crash).

Thus a little feature request : could it be possible to display on output (when launching from the command line) which mk4 file is being read/parsed ? It would be easier to identify the corrupted one.

According to the other bugs I've seen around, I guess this is an upstream problem with metakit not handling correctly corrupted archive files. So it should probably be reported here : http://www.equi4.com/cgi-bin/cvstrac/metakit/rptview?rn=4 but as I said, I don't know how to determine which file is corrupted. I would send it to you if I could find a way...

Update: just found out that removing the archive map and the lock file from ~/.kde/share/apps/akregator/archive solves this keeping all my subscription info intact (but empty).

This looks very much like upstream KDE bug #116482. When the system crashes or when a power outage happens, akregator's archive gets corrupted which causes akgregator to segfault.

And also I'll attach a tarball for the ~/.kde/share/apps/akregator dir which makes possible to reproduce the problem. A little later I'll try to isolate the blaming corrupted file.

same here on Kubuntu Feisty KDE 3.5.7.
Akregator does not start but eats 100% CPU until killed.
Removing my feeds (the OPML-file) "help" in that starting Akregator produces a normal crash.
Only when removing the Archive-folder in .kde/share/apps/akregator, Akregator starts up normally again.
Mine is only 450K so I'll attach it here.
This has happened before already, so I know the procedure, but I don't know the cause. I am using Akregator embedded in Kontact, maybe the Akregator-Archive got corrupted when Kontact crashed.

When shutting down three days ago, there was a kernel panic before syncing the disks.

After that, akregator crashed, too. I'm running KDE 3.5.8, Kontact
Version 1.2.4 (enterprise 0.20070907.709405) on Gutsy.

To resolve this, I deleted two files in .kde/share/apps/akregator: lock and lockPgRNWa.new.

akregator seems to work again now.

I wouldn't say so, because I couldn't find where I could get this ./mku.linux executable.

Another way to detect which mk4 file in ~/.kde4/share/apps/akregator/Archive/ causes Akregator to crash is to use strace to trace the akregator process to find out which file it (opens and) reads last. Just move the corrupted file somewhere else (in case you need to restore the data somehow) to get akregator running again. One might have to do this multiple times if multiple files are corrupt.

When oh when are you KDE guys going to add a decent backend to akregator?! Akregator is destroying my feed data too often and it's getting my the nerves. And there seems to be no recovery option *sob* =[

I don't remember exactly where I got the mku.utility initially, I must have copied it there and later thought Akregator installed it... Anyway, a google search revealed it's part of the mkstats.kit utility http://equi4.com/metakit/stats.html

The correct location of feeds.opml seems to be in ~/.local/share/akregator/data (and not in .kde4 as it used to be in earlier times of this issue).

After a failed resume from suspend to RAM (which since several weeks is a common experience with openSUSE Leap/Tumbleweed with both NVidia and AMD graphics) my feeds.opml got corrupted (Bug 384207).
Is there a backup to be found somewhere may be?

The only backup is feeds.opml~ in the same directory.
