gnome-main-menu crashes when adding to panel

Thank you for your bug. What version of Ubuntu do you use? Could you get a backtrace with gnome-main-menu-dbgsym (https://wiki.ubuntu.com/DebuggingProgramCrash) installed?

I am on Edgy.

Here is the backtrace :

Is this bug a dup of #78146 ?
The problem seems to be the same and both are using Edgy.

I am having the same problem.
It appeared on Edgy and still persists on Feisty.

Thought it had worked for a while, I don't know why it suddenly stopped.

I have tried purging the packet, removing manually files and gconf schemas (on that point not sure that it was done correctly).
I encountered the same problem with the various versions that I downloaded and compiled.

When I add the applet on the panel, just a very thin line appear. It freezes the panel until I killall main-menu.
A few times, after several minutes, I got a correct display but also frozen.

I like this menu and wonder what is going on...

Same with Hardy. It has worked perfectly for months, now, but suddenly it stopped functioning at all. Usually it takes the entire Gnome Panel with it. There were even cases in which it rendered the entire desktop unusable, because I could neither access the Terminal nor the Gnome app launcher via Alt+F2.

The 0.9.9 update made it work, once again. It took hours to load initially (on adding it to the panel the first time), but once that was finished, everything worked perfectly. Even when rebooting it seems to load instantly. Nice performance boost.

I guess, this can be considered fixed.

I got the same error when adding gnome-main-menu:
"OAFIID:GNOME_MainMenu"

however I did 2 installs of 8.04 on the same machine, the first time for some testing purposes the second time as a real install.

The first time I didn't have any trouble whatsoever with adding, the second time I did. The difference was in the configuration settings in /home/username. The first time I added gnome-main-menu BEFORE restoring my entire home-dir from my backup, and the second time I added it after I copied it. And only the second time I got this error.

A few minutes later I discovered that the file attributes (rwx) weren't properly set (due to the copying from backup) and after I did a chmod en chown on my entire home dir everything worked. So if you run into this check your home dir file attributes too!

According to upstream bug, this is fixed in the current supported Gnome releases.
If you have a similar problem on the latest Ubuntu release, please report a new bug.
