Hello,

I know you're really bussy attending other (more) important things, but I'd 
like someone could help me debug this. KDE was working nice until I upgraded 
first to rc5, and then to 3.1 final. 

For those of you who didn't get this message before, my problem is that I 
(almost) can't browse with konqueror (hard drives, network, internet.) Kmail 
also suffers the same ill. In fact, whatever app needs a kio_slave, I end up 
with dozens of processes like these:

        kdeinit: kio_imap4 imap /tmp/ksocket
        kdeinit: kio_http http /tmp/ksocket-
        kdeinit: kio_http http /tmp/ksocket-
        kdeinit: kio_http http /tmp/ksocket-
        kdeinit: kio_http http /tmp/ksocket-
        kdeinit: kio_http http /tmp/ksocket-
        kdeinit: kio_http http /tmp/ksocket-
        kdeinit: kio_http http /tmp/ksocket-
        kdeinit: kio_imap4 imap /tmp/ksocket
        kdeinit: kio_http http /tmp/ksocket-
        kdeinit: kio_http http /tmp/ksocket-
        kdeinit: kio_http http /tmp/ksocket-
        kdeinit: kio_file file /tmp/ksocket-

Right now (before sending this e-mail) my cpu load was 118. I didn't count the 
number of kio* processes but I guess there were up to 50 or more, and they 
never go away. I need to kill them manually (actually I made a script.) The 
problem is, that under some circunstances (yet undetermined,) my kernel 
panices and I need to ALT+PS+s+u+b.

Waldo Bastian asked me for a gdb backtrace and here it is (re post.) Do you 
see something abnormal here? Is that 'cannot access memory..." something I 
need to worry about?

I have also found these under konsole:

        $ konqueror
        kdecore (KLibLoader): WARNING: KLibrary:
        /usr/kde/3.1/lib/libkdecore.so.4:
        undefined symbol: S5LogShowThreadIDS

        Alarm clock


        $ kmail
        kdecore (KLibLoader): WARNING: KLibrary:
        /usr/kde/3.1/lib/libkdecore.so.4:
        undefined symbol: S5LogShowThreadIDS
        
        *** KMail got signal 11 (Crashing)


What's "S5LogShowThreadIDS"??? And why does Kmail crash???

BTW, I'm using Gentoo, gcc 3.2.1, glibc 2.3.1, linux kernel 2.4.20 (gentoo 
patched,) X 4.2.1, Qt 3.1.0. bintutils 2.13.90.0.18. If you need more info, 
please let me know.


Many thanks in advance,
Norberto
