Description O Kullmann 2011-08-13 21:00:09 UTC
Version:           1.6.1 (using KDE 4.6.0) 
OS:                Linux

This happened already now several times (from time to time, but don't know
how to reproduce it): this time, after a reboot 6 of the 11 Dolphin windows were
not recreated.

It seems to be the case that windows who survived several reboots apparently
gain stability, but this time actually some of the old windows, not the newly
created ones, where eliminated.

Otherwise I couldn't observe something special. Okay, Konqueror didn't restart,
but that's usual.

I already leave very few Dolphin windows open due to the permanent problems
after rebooting (redistribution over virtual desktops, and some disappear).

Konqueror is the worst regarding restarting the KDE desktop, nearly always
disappears. Konsole seems best, seems always to reappear. Dolphin is kind of
in the middle.

Reproducible: Sometimes

Steps to Reproduce:
As I said, the disappearing of Dolphin windows happens from time to time
(this time more than usual), but I can't provide more information on that.

The obvious step is, do a reboot (this seems to be more harmful than just
login out and in again).

Actual Results:  
Sometimes Dolphin windows are lost.

Expected Results:  
All the Dolphin windows should reappear (in the virtual desktops).

OS: Linux (x86_64) release 2.6.39.3-0.5-desktop
Compiler: gcc
Comment 1 O Kullmann 2011-08-13 21:19:07 UTC
Actually, this time also many longstanding Konsole windows disappeared;
this happens very rarely.
Comment 2 O Kullmann 2011-08-13 21:22:47 UTC
Hm, perhaps this especially catastrophic reboot might have had something
to do with the fact that a new login-screen was used?
Of course, this is just guessing, but there is nothing else that I can do
than trying like a natural scientist to observe the faulty system (from
the outside).

Would be nice getting at some time some form of response.
Comment 3 O Kullmann 2011-08-25 07:57:17 UTC
The needed solution is an explicit configuration of all windows that
will be reopened at KDE startup, using a configuration file for each
of them in a specified directory. With this KDE would enable the
user to solve this problems himself (but that might not be the
approach of KDE anymore?).
Comment 4 O Kullmann 2011-08-25 08:09:16 UTC
It appears that KDE still "thinks" that the disappeared windows are
still there: when opening a new Dolphin window for that directory,
for which the old window did not open, it appears with a running
number bigger than one. If one relaunches KDE again, also that
Dolphin window disappeared, and creating a new one will have the
running number increased by one. Don't know how often this
can be repeated. The Dolphin windows are visually not there,
and they also do not appear in the System Monitor (while the
newly created ones, with the increased running number, do appear
there).

This is all a manifestation of the corrupted configuration management
of KDE: what is needed is explicit management. Instead it seems that
KDE wants to emulate microsoft, hiding everything from the user ---
which of course doesn't work since KDE is nearly completely buggy (I ran
just through all the KDE applications I use, and the only one where I
do not experience a bug on a daily basis is KOrganizer (but I use
it rarely).
Comment 5 O Kullmann 2011-08-30 10:44:42 UTC
Another crash, again many windows disappeared.
Here some curious observations:

1) Looking closely at that part of the bottom edge, with the various
panels, containing the buttons for the virtual desktops (it might be that this
is called the "pager", but neither left- nor right-click reveals real
context-information), one can see shades (this is unfortunately always rather
obscure, hardly visible) in the size of disappeared windows, while the windows itself are not there! One can also drag these appearances, call them "ghosts",
around to other buttons for virtual desktop, but the ghost itself never
shows up (on the real virtual desktop). What is the spell to make it appear?

2) Whether Dolphin windows are recreated on start up or not, might be strongly
influenced by whether they were active at the time of logging out or not:
it appears that active windows have a good chance to be (correctly) recreated
(not as ghosts), while perhaps those which were not active, but lived in
suspended mode in that part of the lower edge where one can influence windows
(this might be called the "task manager"), are resurrected only as ghosts.

This seems consistent (kind of).

A general question: I wonder what is the status of this bug? Has anybody ever
looked in it?

Resetting assignee to default as per bug #305719
Comment 7 Jekyll Wu 2012-08-24 19:24:28 UTC
Since KDE SC 4.7 dolphin switch to the "one window one process" model.  Could you recheck the problem with KDE SC 4.7+ ? 

Personally, I have never encountered or noticed this kind of problem.
Comment 8 O Kullmann 2012-08-25 11:29:01 UTC
Hello,

as soon as Suse 12.2 is out, I will report.

Comment 9 Adrián Chaves (Gallaecio) 2012-11-01 16:47:20 UTC
It seems it is out already :)

Could you please check whether or not it works?
Comment 10 Julian Steinmann 2018-03-30 09:37:18 UTC
@O Kullmann, is this still a problem in the newer versions of Dolphin / KDE? If not, I'll close this bug soon.
Comment 11 Julian Steinmann 2018-04-15 16:03:44 UTC
No response -> closing. Thanks for reporting this bug, please reopen the report if you can still reproduce this behavior with newer versions of Dolphin.
