Lately, Konq crashes every time I try to view the history from the sidebar............this is a fairly recent development. All the other button at the sidebar work.

Anyonw know how to correct this? Here's a backtrace: [code:1](no debugging symbols found)...(no debugging symbols found)...

UPDATE

I've narrowed the problem down to the $HOME/.kde/share/apps/konqueror/konq_history file. This file becomes bad only after visiting an http base URL.

For example, If I visit the Slackware homepage using <http://www.slackware.com/> for the URL, Konq will crash when trying to view the history in the sidebar. However, if I use the URL <http:/www.slackware.com/index.php>, Konq will not crash when I view the history in the sidebar. Note: I first have to remove the konq_history file, clear it from the Control Center (Control Center -> Internet & Network -> Web Browser -> History Sidebar) or clear it from the menu (Settings -> Configure Konqueror -> History Sidebar) after the konq_history file becomes bad.

I noticed that this only happens with http URLs. For ftp URLs, there is no problem.

Looks like a likely candidate for a bug report.......

FIXED

I finally found the problem. It wasn't a bad konq_history file, but the creation of 0 byte .png files found in the $HOME/.kde/share/cache/favicons directory. These .png files are used by the history file to create custom icons in the history sidebar.

A workaround is to remove any 0 byte .png files in the favicons directory. I still haven't got a clue as to why these 0 byte files are being created in the first place, tho'.

rmfavicons SCRIPT

Here's a bash script I whipped up to make it easier removing the troublesome .png files for anyone interested.
[code:1]#!/bin/bash
#-------------------------------------------------------------------------------
# Filename: rmfavicons
# Date: 26 Jan 2004
# Written by: CTWaley
#
# Remove all the 0-byte .png files found the the user's
# $HOME/.kde/share/cache/favicons directory to prevent Konqueror from crashing
# when trying to view the history from the sidebar.
# This script can be used for a cron job, on a hourly basis, to automatically
# remove the 0-byte .png files.
#-------------------------------------------------------------------------------

## Begin script ##

# Make sure the favicons directory exists in the user's home .kde directory.
if [ -d $HOME/.kde/share/cache/favicons ] ; then
# Now to find all the 0-byte files found in the favicons directory
# and remove them.
for i in $( 'ls' $HOME/.kde/share/cache/favicons ); do
if [ ! -s $HOME/.kde/share/cache/favicons/$i ] ; then
rm $HOME/.kde/share/cache/favicons/$i
fi
done
fi [/code:1]

Hmmm.........it seems the location for the favicons directory has moved with the new release of KDE 3.2. It's now located at $HOME/.kde/cache-<hostname>/favicons. I've updated the script and put the path in variable for easier updating in the future (if necessary): [code:1]#!/bin/bash
#-------------------------------------------------------------------------------
# Filename: rmfavicons
# Date: 26 Jan 2004
# Written by: CTWaley
#
# Remove all the 0-byte .png files found the the user's
# $HOME/.kde/share/cache/favicons directory to prevent Konqueror from crashing
# when trying to view the history from the sidebar.
# This script can be used for a cron job, on a hourly basis, to automatically
# remove the 0-byte .png files.
#
# Update: In KDE 3.2, the location of the favicons directory seems to have
# changed. It is now "$HOME/.kde/cache-<hostname>/favicons"
#-------------------------------------------------------------------------------

## Begin script ##
host=$( echo $HOSTNAME | awk -F. '{ print $1 }' )
favdir=${HOME}/.kde/cache-${host}/favicons

# Make sure the favicons directory exists in the user's home .kde directory.
if [ -d $favdir ] ; then
# Now to find all the 0-byte files found in the favicons directory
# and remove them.
for i in $( 'ls' $favdir ); do
if [ ! -s ${favdir}/$i ] ; then
rm ${favdir}/$i
fi
done
fi [/code:1]
