unity-applications-daemon crashed with SIGSEGV in gee_list_list_iterator()

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

When I'm, starting unity applications menu, crashed

Same happens for me, only I don't have to click the applications button, the unity-applications-daemon crashes right after login.

Full stacktrace:

Right after login,the unity-applications-daemon crashes. I don't have the applications button

Ummm... I thought it was bad form to have the coredump still on the bug?

Similar problems here, running an eeePC 1005ha. At the moment I'm stuck running the default programs (clicking on these works OK). Trying the ubuntu icon in the upper-left corner brings up the search bar and a list of application categories, but clicking on any of these, or typing anything into the search bar, causes the screen to flicker and reset (behaviour similar to doing compiz --replace or metacity --replace). The same happens if I click on the applications icon on the left-hand side.
At the moment this completely breaks things for me: aside from firefox I don't use any of the default 'favourite' applications and I can't access any of the others. (Correction: I managed to get a terminal window open and I can now check my email by running thunderbird from the terminal. The downside is that while running from the terminal, there's no icon that appears on the left-hand bar, so I can't pin it to the bar.)

After update, I conferm when click on unity applications menu or on one of the unity applications menu and then Xserver crashed

Impossible acces to applications and/ or typing anything into the search bar,

After update, when click on unity applications menu or unity applications menu Xserver crashed

In my case I'm not sure if it's a complete crash of Xserver, but the window manager definitely resets. I'm waiting for the fix to make it into the updates to see if that gets things working.
Is anyone else finding that right-clicking on icons in the Unity launcher doesn't have the desired effect? It may be a completely different bug but I find that right-clicking often does nothing at all, and the rest of the time, I get a blank bubble. (For example, if I run a program - using a terminal command - that's not in the favourites list, but that I would like to have available on the left-hand side, I right-click the icon, expecting to see a 'pin to dock' option, or something along those lines. Instead I get a bubble with a horizontal line, and a thin blank space above and below it. I found that if I click on the blank space below the line, I did succeed in pinning the icon, but there's no text showing up in the bubble. (On the other hand if I put the mouse cursor over an icon I get a bubble with the name of the program.)

I am having this is something very like it too, on RC 10.10 & final release. I am running an IBM Thinkpad X31. The entire desktop restarts if I even mouse over any icon in the "dock", making it completely unusable. It is not even possible to logout; clicking on that menu causes a restart, too.

As another sufferer has commented, I don't think X is restarting, but the whole WM & desktop does. Open apps survive but as clicking on them causes a restart they are unusable.
