Status in Do Plugins Project: Incomplete
Status in “gnome-do” package in Ubuntu: Confirmed

Bug description:
I am running gnome-do 0.8.2 using the docky theme on ubuntu karmic.  The version in synaptic is 0.8.2.1+dfsg-1~ubuntu1 .  I am using the ppa at ppa.launchpad.net/do-core/ppa/ubuntu

When I try to use the opensearch plugin gnome-do crashes.  Specifically,

1) super-space to activate gnome-do.
2) type 'web' to select the web search plug-in.
3) tab to the next pane and type a phrase.
4) hit enter

This sequence should open firefox (or a new tab) with the search results from the specified search engine.  Instead, immediately after I press enter gnome-do crashes.  I ran gnome-do from the terminal and the following error was printed:

[Error 07:40:51.002] An error has occurred in UpdateEvents

When I tried to test using other search engines no search engines appear in the third pane.  There was an update to both gnome-do and firefox this morning so it could be the result of some change to the search engine locations during the firefox update.

I have tried other gnome-do searches and it seems to be able to launch programs and documents as normal.  I have tried the classic theme and the same error occurred.
