Hi All,

I am running krusader-1.90.0-1.el5.rf (kdebase-3.5.4-19.el5.centos.1) under XFce 4.4.2 on CentOS 5.2 (uname -r 2.6.18-92.1.22.el5). I do not have a choice of upgrading KDE: that is just how CentOS works.

Problem: when I start krusader, or any other KDE application for that manner, I get the following error message:

Could not find mime type: application/octet-stream

How do fix this?

Many thanks,
-T

Is the shared-mime-info package installed? Also try rebuilding the sycoca:

Code: Select all

kbuildsycoca --noincremental

Code: Select all

# rpm -qa *shared*
shared-mime-info-0.19-5.el5

Uninstalling it and reinstalling it did not help

Also try rebuilding the sycoca:

Code: Select all

kbuildsycoca --noincremental

No symptom change.

Under root (which does not have the problem):

Code: Select all

# kbuildsycoca --noincremental
Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed
Warning: kbuildsycoca is unable to register with DCOP.
kbuildsycoca running...
Link points to "/tmp/kde-root"

Under user todd:

Code: Select all

$ kbuildsycoca --noincremental
Warning: kbuildsycoca is unable to register with DCOP.
kbuildsycoca running...

Poop!

These messages are worrying:

I believe the permissions on your user profile are likely damaged, due to use of the root account. If you are not attached to your KDE settings:

Code: Select all

rm -rf $(kde-config --localprefix)
rm -rf  ~/.dcop* ~/.DCOP*

Otherwise ensure that all files are owned by your user, and remove the DCOP ones anyway.

I am running under XFce 4.4.2. I only have KDE running on a kunbuntu virtual machine (love it by the way, so ready for the general public, now for some apps!)

Code: Select all

$ su
# cd ~todd
# chown -R todd.users .

# find . -iname *dcop*
./.DCOPserver_rn1.rent-a-nerd.local_:0
./.DCOPserver_rn1.rent-a-nerd.local__0

# find . -iname *dcop*
./.local/share/Trash/files/.DCOPserver_rn1.rent-a-nerd.local_:0
./.local/share/Trash/files/.DCOPserver_rn1.rent-a-nerd.local__0
./.local/share/Trash/info/.DCOPserver_rn1.rent-a-nerd.local__0.trashinfo
./.local/share/Trash/info/.DCOPserver_rn1.rent-a-nerd.local_:0.trashinfo

No symptom change. Poop!

Is a new user affected?

No.

This fixed the problem:

Code: Select all

[todd@rn1 ~]$ mv .kde .kde.000
[todd@rn1 ~]$ mkdir .kde

Thank you for all the help. Your having me test a different user was what led me to see all the things being created in .kde. So I started Todd's .kde over fresh.
