[gnome3]winff causes crash of gnome-shell

[Fabio Marconi]

Binary package hint: winff

Starting conversion from avi to dvd, resizing, after a couple of minute gnome-shell crash with this output:
Warning of the window manager: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x1600075 (WinFF)
Warning of the window manager: meta_window_activate called by a pager with a 0 timestamp; the pager needs to be fixed.
Warning of the window manager: Log level 16: invalid uninstantiatable type `(null)' in cast to `GObject'
Warning of the window manager: Log level 8: g_object_get_data: assertion `G_IS_OBJECT (object)' failed
Warning of the window manager: Log level 8: g_ascii_strncasecmp: assertion `s2 != NULL' failed
Shell killed with signal 11

winff still working on the restored gnome 2 session

Version 1.2 on Ubuntu Maverick

Can you please test if this is reproducible? If so, what exactly do you need to do to have it crash? Does it also crash when you start from a terminal (what is the output there)?

Most text in your report are WARNINGS... they should not crash your session. Are you sure they are related, i.e. do they ONLY and ALWAYS happen when the crash occurs?

Seems like this bug belongs to the gnome package.

Hello Paul
Yes, I can reporduce it.
I've found that ffmpeg is running at 100% of cpu, when shell crash, and winff don't crash, go on in his work.
The messages in the shell terminal:
Avviso del window manager: Log level 16: STACK_OP_ADD: window 0x1200012 already in stack

When possible i will try on another machine to see if reproduceable there too.
Thanks

That is good. So now I guess I need to create GNOME3 environment to
test... Or can somebody else test this as well?

Of course ffmpeg is running high. Converting videos is an intensive task.

I am not exactly sure how, but could you try to make sure the messages
are in English next time? See also:
https://help.ubuntu.com/community/DebuggingNonEnglishErrors

I think Avviso means "warning"? Than that should NOT be the cause of the
crash.

> When possible i will try on another machine to see if reproducible there too.

Did this yield any information?

I still believe this bug should be reported to gnome3 instead of winff,
are you convinced it is winff's fault?

[Fabio Marconi (fabiomarconi)]

Tomorrow i'll retest this, and i'll look into system logs to see if there's some oom.
Sorry if i've posted the terminal output in italian but is exactly the same of above.

Fabio,

Any news?

I tried to reproduce this problem but running winff from gnome-terminal and converting an AVI to a DVD preset does NOT result in a crash on my machine.

You could help by explaining in more detail exactly what you do to get the crash. I.e. how you start winff, what buttons you press, what exact preset you use.

What do you mean with "GNOME3"? I installed gnome-terminal, but that is version 2.32.0-0ubuntu1 The only package with gnome3 in the name is gnome3-session. Is that what you mean?

Output in gnome-terminal (warnings are always there and not a problem):
paul@stromboli ~ $ winff
