clicking window menu button/icon on title bar kills decorator

[karashata]

1) Linux Mint 11 'Katya'
2) Click the window menu button/icon on the title bar
3) gtk-window-decorator crashes with a segmentation fault, window decorations end up disappearing. Below is the exact error:

** (gtk-window-decorator:2345): CRITICAL **: Could not find frame info \xf0\xbc\u000d\u0002 in frame type table
Segmentation fault

4) It should open the window menu
5) It always happens without fail

I believe the error below relates to this one

 unity-window-de[2149]: segfault at 318 ip 0000000000415d6f sp 00007fff2301ff90 error 6 in unity-window-decorator[400000+1b000]

This also happens on Katya, randomly.
The service "unity-window-decorator" can be restarted - and then the minimize-maximize-close buttons, and the upper window frame (in the proper way) are back and functional.

I have the same problem. I also have a problem with another program causing a segmentation fault on "/usr/lib/libgtk-x11-2.0.so.0" I am not sure if they are related or not, but the program crashes just like the window decorator. Maybe it's driver related?

I'm using a Dell Latitude XT with Radeon graphics card.

Same here. Using Katya, 64-bit build.
There are also some problems with GTK themes on Katya, don't know if they are related.

This also happens for me, but only with compiz. When using metacity, the crash doesn't happen.
I'm using a Radeon HD 6870 with the fglrx driver and the default Mint theme, in case it has anything to do with either of these.

[Aaron Anderson (anderson-aaron)]

@David: Looks like it does not happen for me when I'm using metacity. Must be a compiz bug. I am using whatever the default drivers are for this card "ATI Technologies Inc Radeon Xpress 1250"

[Eric Thompson (eric-lowvoltagelabs)]

I'm seeing this same problem, the crash also happens using the shortcut key alt-spacebar. My system has an Nvidia card running the current version of the proprietary drive. I have not tried other drivers.

I can restore the window decoration by going to "CompizConfig Settings Manager" > Disable "Window Decoration" > Enable "Window Decoration". I've not found any Compiz settings that cause the problem to not happen.

Let me know if there are debug/log files I can provide to help.

I 'm using Linux Mint 11 'Katya' 64-bit build.
Exactly the same problem - it is a very annoying problem,
when you accidently click on the top left of a window, it always happens.
however it is very easy to repair (disable/enable window decoration) it always happens !

[macko (erdosboti)]

The same thing happened to me, but the strangest thing was that it started after some package refreshment and never happened before that. I found something that solved the problem for me and maybe helps you as well. I changed the "CompizConfig Settings Manager" > "Window Decoration" > "Command" to
"/usr/bin/compiz-decorator" (I don't remember what it was set to before)
This solved the problem for me

[Christiaan Bouter (c-bouter)]

I dit the same (/usr/bin/compiz-decorator), but the problem was still there.
I have changed the compiz version from 0.9.4 to 0.8.6 (the old one) and the
problem is gone now for me. I had to make a news startup-application:
the starting of compiz.
At this moment al is fine; however it is a strange workaround !

[tsh (tsh)]

I get this in ubuntu 11.10

Is there a way to disable/remove that button?

[Michael M. (michael-muhn)]

+1
I for now force-feed
unity-window-decorator --replace
to my installation via a startup srcipt. (I'm somehow not able to set it as default).
Since it does nothing else than replacing the gtk-window-decorator, someone could set it as default for the next Mint incarnation.
Also, I wonder why this bug is still new / undecided / unassigned.
