Kmail crashes since yesterday randomly and often. Error message:
KCrash: Application ‘kmail’ crashing… crashRecursionCounter = 2
You’ve mistakenly made a global color change to gray 0 within nested colors
on page 1. Will try to recover.
dvips: Problems with file writing; probably disk full.
Speicherzugriffsfehler (Speicherabzug geschrieben)
The disk isn’t full (hundreds of GB free).
OK, DrKonqi sends crash messages. But since kmail crashes every hour, DrKonqi causes high load on the machine, making it even more difficult to go on working.
So, for the time being, after the PC sent at least five crash reports, how can I disable that behaviour?
Instead of shooting the messenger i would try to find out why kmail crashes. There are several hints which should be investigated…
What changed since yesterday? Updates? Colors schemes? File permissions? Disk space? What did you change on your system yesterday? Does it also happen with a fresh user profile? How do you upgrade your system? Do you have additional 3rd party/home/developement repos? …

Thanks for suggestions. As nobody else seemed to be bitten by a crashing kmail, I reinstalled tumbleweed from scratch this afternoon. There were more glitches and now, after two and a half hours everything is back to normal, except that the letters on the screen seem to be cleaner. In Emacs it really makes a difference.
Every four or five years it’s worth the time and effort.
Nice exercise! There was some abnormal activity on Infamous Host Erlangen too:

I ran akonadictl fsck and akonadictl vacuum which stopped akonadi dumping core. When kmail still dumped core I ran zypper ps -s and found lots of processes using deleted files. I opted for reboot which stopped core dumping at all so far.
Kmail search in some 9 GiB of local mail was sluggish on Mar 18. Now it’s fast again as it has been since a decade.
Regarding baloo search: I’ve got around 30 GB Mails on the system. Once in a while I delete the baloo database (for any other reader except Karl: don’t delete your emails!!!) and rebuild it, which makes it much faster and smaller.
