Description Silvano 2005-11-18 20:04:50 UTC

Version:            (using KDE KDE 3.4.2)
Installed from:    Mandriva RPMs
OS:                Linux

kded crashes and restarts every few seconds. 
After about 50-60 times he tries to restart itself, it USUALLY stops to restart!
The backtrace is the following:

(no debugging symbols found)
Using host libthread_db library "/lib/tls/libthread_db.so.1".

`shared object read from target memory' has disappeared; keeping its symbols.

The crash has reported the signal 8 (SIGFPE)

I tried to start kded from the shell, and I've received this "responses":

[silvano@Sirio ~]$ KWrited - listening device /dev/pts/1

kded:  Created engine, scheduler and read catalogs

[silvano@Sirio ~]$ Last DCOP call before KDED crash was from application 'kded'
to object 'KDirNotify-4', function 'FilesChanged(KURL::List)'.
KCrash: Application 'kded' crashing...

THIS several times :)

Thank all for any eventual idea :D

I also use Mandriva RPMs, but I am running on the 'Cooker' KDE 3.5.1: and the problem happens here too. Not sure if it's something about Mandriva's packaging. But you have it shown here as a KAT issue?

Can I make the problem go away by removing Kat?

Comment 3 rick stockton 2006-02-05 11:01:18 UTC

I forgot to mention... in my case, I have many concurrent instances of kded: they've all fallen into the crash handler, except for one which is actively running (for a few moments).

Comment 4 rick stockton 2006-02-06 21:56:58 UTC

I should be in a different bug, my occurences are all SIGSEGV.

HOWEVER: I renamed /usr/bin/kat as "kat-save", and created an empty "kat" file (not even executable). Instead of crashing and restarting 40 times, it now gives up after just a couple of tries. It would be REAL NICE, however, if KDED was modified to:

1) check that "kat" exists, and if not: 2) bypass invoking it.

This would be REAL NICE, because KDED is also responsible for many other things. 


I followed Mandriva instructions to create a file ".mdv-no_Kat" in $HOME, and it had NO EFFECT on the KDED crash loop (I was still looping 40 times with that file present). But maybe that workaround was (accidentally, IMHO) not brought forward to the Cooker 3.5 Version.

Comment 5 Ivica Culjak 2006-02-18 20:16:01 UTC

I have reported the same problem in bug report #118080, so you can have look at that report number. It's backtrace dump is pretty similar to the one reported here, and it is also shown as signal 8, (SIGFPE). My report is listed as UNCONFIRMED, so maybe if you add comments to it the problem should be looked into.
