Bug 191167

If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? Thanks :)

Sure. Thanks for the tip. Always wandered, how to obtain a stacktrace.

Same here. Over Debian Sid package.

As already noticed, removing the configuration folder ~/.kde/share/apps/krusader is not enough. 
But however krusader works properly if started in superuser mode.

Hope it helps.

I've got the same problem:

#6  0x08085ee7 in _start ()
____________________

My configuration:
Mandriva 9.1 powerpack, KDE 4.2.2, Krusaderf 2.0.0
krusader works properly if started in superuser mode.

removing the configuration folder
~/.kde/share/apps/krusader doesn't solves the problem.

system: Debian testing
kde: 4.2.2
krusader: 2.0.0 

Got the same problem several times. In my case, the source of it is bad [Startup] section in krusader configuration file
~/.kde/share/config/krusaderrc

Somehow, from time to time, active tab index became "out of range", as in example below for left panel: active tab index = 2, it mean third left active panel, but only two exists in "Left Tab Bar" 

[Startup]
Left Active Tab=2
Left Panel Popup=0
Left Side Is Active=false
Left Tab Bar[$e]=/mnt,/opt
Left Tab Bar Props=0,0,0
Left Tab Bar Types=0,0,0
Right Active Tab=0
Right Panel Popup=0
Right Tab Bar[$e]=/ext/tmp
Right Tab Bar Props=0,0,0
Right Tab Bar Types=0,0,0
Vertical Mode=false

Workaround in this case obviously is this: manually edit configuration file and set wrong active tab index to zero.

And imho krusader should not crash, no matter whatever data contained in config.

same for me (from gnome). it started to behave weird in ubuntu 9.04 around october (i always auto-update to latest packages). upgrade to 9.10 did not help.

thanks for hint with -left -right options.

From bug 222023:
--
What I was doing when the application crashed:
Until yesterday krusader run very well, then I have changed compiz features,
themes and system fonts and I have changed something about the default function
keys on the gtk libraries. I have changed also a lot of krusader settings and
it continue to run.
This morning I have switched on my computer and krusader crashes all the time.

*** Bug 222023 has been marked as a duplicate of this bug. ***

Confirmed on Gentoo (kde 4.4.0, krusader 2.0.0).

Also had problem with:
Right Active Tab=3
while there were only 3 tabs in right panel

Problem occurred when i quickly closed two instances of krusader one of which had 4 tabs in right panel, causing indefinite state in krusaderrc

- you need to develop or fix locking mechanism when multiple instances of krusader wants to write to configuration file

- you should be able to ignore bad values for 'Right Active Tab' and possibly other not-critical config parameters

Confirmed on Gentoo with kde-4.4.4 and krusader-2.0.0-r1
Maybe as a workaround a quick check in the config-loading part could be added to see whether the stored left/right active tab is actually existing, or else reset it to 0?

Krusader doesn't crash with a wrongly saved tab number on 2.2.0-beta1 anymore. Please try the new version.

The update to 2.2.0-beta1 fixes it for me, thanks :)

Krusader is closed with an error at startup. An error occurs when the last run of the leave in one of the windows show the contents of removable disk usb and close krusader, this is not unmounting removable disk usb. Tried to remove the path to the last opened directory and manually edit the configuration file "~ / .kde / share / config / krusaderrc" in the section "[Startup]" parameter of "Left Tab Bar" or "Right Tab Bar". Placed manually in the parameter "Right Tab Bar [$ e]" value "/, $ HOME". But it did not help and the next time the error again.

Hi,
it's seems that the bug is still there :
after a crash of my computer (freeze after unmonting an external HDD..) I manualy restarted it (by a reset). Then Krusader didn't wanted to start!
I've edited the file krusaderrc : active tab index=2, but only 2 exists!
I added a tab, and it's now ok.

So it means that the bug is still here, isn't it?

Precision : I'm on Mageia (not ubuntu)

Jean-Michel,
What Krusader version do you use?

Hi,
I use : "Version 2.0.0 "Mars Pathfinder"
Utilisation de la plate-forme de développement de KDE 4.6.5 (4.6.5)"

Thanks for the response,

Krusader ver 1:2.0.0-1ubuntu3         running in a Kubuntu environment.

Jean-Michel, Kirk,
You will need to update to Krusader-2.2.0-beta1 or higher. Since I don't use Mageira or (K)Ubuntu I can't tell you what the best way to achieve this is.

Sorry, I haven't seen that the fix was in the beta version, so I've haven't seen that my version was older (but latest stable) than the fix!
So I've have installed krusader-2.2.0-beta1 (with tarball, since it's not in my reposetory). Then I (wrong) edited the file krusaderrc in order to provoque the crash.
Results : It's ok!!

thanks (I think I will install the version krusader-2.4.0-beta1 now :-) )

Thank you Steffen.

I'll install

Krusader-2.2.0-beta1  or higher.

Let's assume this bug is solved.

If I have similar issues with the beta version, I'll resend with the same bug number.

have a great week ahead,
Kirk

I think Krusader began to crash after I installed an nfs-kernel-server (or something having to do with setting up my an nfs server from the same computer).  Now it crashes every time on its startup
