gnome-session-remove comand line tool not working

[Dani Alonso]

Binary package hint: gnome-session

gnome-session-remove --list outputs an empty list and hangs the shell.
gnome-session-remove anything also hangs

[Sebastien Bacher (seb128)]

Thank you for your bug. The description lack basic details, what version of Ubuntu are you using? Does it happen every time? Could you describe easy steps to trigger the issue?

[Dani Alonso (dalonso)]

I'm using hardy with gnome-session updated to 2.21.90-0ubuntu2.

It happens every time. To reproduce, open gnome-terminal and type any of the commands above.

[Sebastien Bacher (seb128)]

Could you try to obtain a backtrace http://wiki.ubuntu.com/DebuggingProgramCrash and attach the file to the bug report?

[Dani Alonso (dalonso)]

Sorry but I can't install the debug version of gnome-session package because it's not updated to the actual version:

gnome-session --> 2.21.90-0ubuntu2
gnome-session-symdbg --> 2.20.0-0ubuntu2 !!!!

What should I do?

[Sebastien Bacher (seb128)]

Do you have the hardy dbgsym source?

[Dani Alonso (dalonso)]

That is what I was trying to say:

I cannot install gnome-session-symdbg-2.20.0-0ubuntu2, the only version in the repositories, because it is depending of gnome-session of the same version and conflicts with gnome-session-2.21.90-0ubuntu2 of the repository.

[Sebastien Bacher (seb128)]

the current version available on hardy is gnome-session-dbgsym 2.21.90-0ubuntu2, what architecture do you use?

[Dani Alonso (dalonso)]

Sorry, I found the cause of the problem, I didn't replaced the "gutsy" in "deb http://ddebs.ubuntu.com gutsy main universe" with a "hardy".

But now how can I get a gdb backtrace if the program is not crashing. It simply stalls without any output.

Instead of a backtrace, I have run it under strace and the output shows it stalling at a poll operation, untill I kill it with ^C

I'm attaching the output of "strace gnome-session-remove --list".

[Sebastien Bacher (seb128)]

could you get a backtrace using gdb? just run the software in the debugger, ctrl-C when it's hanging and get backtrace there

[Dani Alonso (dalonso)]

Ok, attaching the backtrace.

[Sebastien Bacher (seb128)]

that's a strace not a gdb stacktrace

[Dani Alonso (dalonso)]

Oops, sorry, I attached the strace again. Here it goes the backtrace.

[Sebastien Bacher (seb128)]

the stacktrace has no debug informations

[Dani Alonso (dalonso)]

Well, I already stated that the program is not crashing. This is what gdb gives as a backtrace when ctrl-C

[Sebastien Bacher (seb128)]

what I mean is that you don't have libglib2.0-0-dbgsym libgtk2.0-0-dbgsym etc installed so the backtrace lacks details

[Kurt Peterschmidt (kurtpete)]

I can confirm this is happening in the x64 release install of Hardy as well.

[beaudoin996 (beaudoin996)]

I got exactly the same problem. It started with the hardy update.

When I type :

gnome-session-remove gnome-panel

the terminal just hangs on and I have to type Ctrl-C to move on.

When I type :

gnome-session-remove --list

the terminal hangs on but I see a message telling me that registered clients list is empty.

[Nick Weedon (nick-weedon)]

I have the same problem also.
I have installed all debug symbol versions of relevant libraries and dumped a gdb backtrace (attached).

[Nick Weedon (nick-weedon)]

I forgot to mention, i am running Ubuntu Hardy (originally installed as Ubunutu Feisty but upgraded twice).

uname -a =
Linux wyvern 2.6.24-17-generic #1 SMP Thu May 1 13:57:17 UTC 2008 x86_64 GNU/Linux

[Nick Weedon (nick-weedon)]

Oh, and the package versions:
gnome-session 2.22.1.1-0ubuntu2
glib2.0-0 2.16.3-1ubuntu2

If you need any more information, please let me know.

[Martin Mai (mrkanister-deactivatedaccount-deactivatedaccount)]

We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

[Nick Weedon (nick-weedon)]

Hi Martin,
The latest Ubuntu release does fix this issue in the sense that i can no
longer reproduce the problem since the "gnome-session-remove" utility is
now completely missing from the "gnome-session" package (in Ubuntu
Intrepid) and cannot be found anywhere in Ubuntu intrepid (in any other
package).
Not really the sort of fix i was looking for however...

Thanks,
- Nick Weedon

And how I can remove my saved session, I don't want to remember my session anymore, but I can't disable this feature, every time I start my machine the computer shows the last saved session, even with "Automatically remember running applications when loggin out", I wish an additional "Forget saved session" button
