Using unity-launcher crashes Unity and causes a reload.

[Owais Lone]

I upgraded Unity yesterday and am facing this problem. Whenever I try to use the dock, it crashes and everything is reloaded again. I'm on Maverick with latest updates using an Intel 965GM and the CLUTTER_VBLANK=none hack to workaround the white screen.

[Didier Roche-Tolomelli (didrocks)]

Jason is currently looking at it, it seems (issues with 965GM)

[Didier Roche-Tolomelli (didrocks)]

ok, we can probably consider it as a SRU, can be get a backtrace of the issue, please?

and simply segfaults when trying to use the launcher.

If you want anything else, do tell me from where to get. :)

[Didier Roche-Tolomelli (didrocks)]

Here are the infos to get a backtrace : https://wiki.ubuntu.com/UnityFilingBugs

Just cooked :)

[CLI (m-wichtowski)]

Fresh Maverick Netbook install on EeePC1000HE.
1/ start Firefox,
2/ close Firefox just after it is up and running,
3/ unity crashes and reloads.
I'll make some gdb logs if I'll find opportunity (this is not my netbook :( )

[lasombra (lasombra)]

This issue happens on Maverick (fully updated). The issue is as follows: While moving mouse from one icon to another or from an icon to the desktop, the restart occurs. It does not happen moving to an icon from outside (means moving from the desktop to an icon on the sidebar).

This is still not a backtrace:
Please see:
https://wiki.ubuntu.com/UnityFilingBugs

[Owais Lone (loneowais)]

Since we are moving to Compiz, I think working on this is a waste of time and resource. Shouldn't it be marked invalid.

[Owais Lone (loneowais)]

oops, i forgot there are people on Maverick using mutter unity. Sorry.

[papukaija (papukaija)]

It's difficult to get a backtrace since, at least for me, this bug happens randomly, but most offen when closing an application.

[papukaija (papukaija)]

Btw, this bug is similar to bug 634701.

[Michael Kogan (michael-kogan)]

I'm observing this bug on a Thinkpad X40 with Intel GM855. Unity reproducibly crashes every time I hover the dock with the mouse pointer. Unfortunately the UnityFilingBugs wiki page didn't really work here (no mutter.log file was created) so I just ran gdb with tee (like "gdb mutter | tee mutter.log"), see attachment.

[Mauricio Andrés (mauricioandres288)]

I have the same problem, I'm starting like Unity, just fix that problem

[Omer Akram (om26er)]

how about we close this bug as 'wontfix' ;) since unity moved to compiz this issue should not be happening.

[Didier Roche-Tolomelli (didrocks)]

right, there are little change it will be fixed in natty since we can't affort changing the driver or mutter there.

[Michael Kogan (michael-kogan)]

And what do maverick users do?

[papukaija (papukaija)]

Is this the right way to triage bugs? What those affected by this bug will do until Natty gets released?

[papukaija (papukaija)]

There seems to be a PPA with Compiz based Unity (both for Maverick and Natty) at https://launchpad.net/~unity/+archive/ppa

[Didier Roche-Tolomelli (didrocks)]

We are really sorry for maverick users getting this bug (which isn't the majority, but still a lot of them, even on ATI card), but the time we would take to fix this bug in maverick will prevent to do a first class natty experience.

There is still the ubuntu desktop session in gdm to get the GNOME environment on maverick, or the netbook-launcher present in Lucid for a netbook environment. In any case, seeing this crash, I don't think maverick users having it is using unity mutter under maverick right now.
