Sentry Crash Report:

Description Richard Clayton 2005-08-11 04:15:34 UTC 
Version:            (using KDE KDE 3.4.0)
Installed from:    SuSE RPMs
Compiler:          gcc 3.3.5-5 
OS:                Linux

Proxy access is needed for certain sites via my LAN. manual config of my proxy works fine (settings-configure konqueror-proxy) and once details are inputted browsing via proxy is possible.
To quicken this process I want to use the 'enable proxy' button. Pressing this button closes the instance of konqueror that is open but not other instances.

This problem is reproducible everytime over several days and reboots. I have a similar button added to firefox with the same proxy, works fine.
 
A crash handler report is generated and I have included it below :)

Comment 7 Stefan Monov 2005-10-15 06:46:19 UTC 
Bug 114416 has been marked as a duplicate of this bug. I believe that this was done by mistake. In 114416, the crash is triggered by a hotkey. Here, the crash is triggered by a button. So I'm asking - does "button" as used here mean a toolbar button or a hotkey? If it means a toolbar button, then the two are separate bugs.
Comment 8 Thiago Macieira 2005-10-15 19:37:25 UTC 
The crash is not triggered by the fact that it is a shortcut or if it is a button on the toolbar. The act of enabling the proxy crashes Konqueror, so it's the same bug.
Comment 9 Stefan Monov 2005-10-15 22:43:06 UTC 
Then why in Bug 114416 it *never* crashes when the proxy is toggled via the "Configure Konqueror..." dialog?
Comment 10 Elan Ruusamäe 2005-12-30 19:45:55 UTC 
i've have bind F12 key to the "disable proxy" feature, crashes here with 3.5.0
Comment 11 Stefan Monov 2006-01-23 13:45:56 UTC 
My Konqueror 3.5, built from SUSE Linux 10.0 RPMs still crashes.
Comment 12 jpg 2006-12-06 13:29:23 UTC 
New precision about this bug

If I (des)activate the proxy by the shortcut first, Konqueror crashes immediatly.

Each time, I (des)activate the proxy by the menu, everything goes well.

If I (des)activate the proxy at least one time by the menu, then the shortcut does not crash Konqueror anymore for the session.


I use KDE 3.5.5.

do you still experience this bug under kde 4.4 or 4.5 ?
Comment 15 jpg 2010-08-31 12:05:40 UTC 
The functionality does not exist anymore in konqueror/kde 4.4.5 (Debian 
testing updated today) or am I wrong ?

Comment 16 Christoph Feck 2011-06-26 14:28:53 UTC 
This crash is from the KDE 3 version, which is no longer maintained. If you are experience crashes with the KDE 4 version, please attach an updated backtrace or report a new bug.
