Bug Description

Binary package hint: kdebase-workspace

Description: Ubuntu lucid (development branch)
Release: 10.04

Since getting the 4:4.3.90-0ubuntu2 packages for Ubuntu Lucid, Plasma is crashing any time I interact with it. It allows me to perform an action, like open a folder from the quick folder access or expand the notification area, but immediately crashes after the action is complete.

Apport retracing service (apport) wrote on 2010-01-12: Possible regression detected

This crash has the same stack trace characteristics as bug #405463. However, the latter was already fixed in an earlier package version than the one in this report. This might be a regression or because the problem is in a dependent package.

Could you install kdebase-workspace-dbg and get a crash log from the KDE crash handler, which should pop up when plasma-desktop crashes for the first time?

I installed all the debug packages, crashed plasma and hit the "developer
information" tab. It said "This crash information is not useful" and
"Application: Plasma Workspace (plasma-desktop), signal: Segmentation fault"

The "Install Debug Symbols" button is greyed out, indicating I have all the
necessary debugging symbols. If I try to re-load the crash information, the
crash handler crashes.

Never mind, creating a new profile solves the problem. Thought it was a bug because it happened on both of the machines I'm testing Lucid on, but if blowing away my profile solves it, it's probably not a bug.

When I set my profile back up it does it again. I think it might have something to do with multiple panels because it started crashing again once I added all my panels back.

Attached is a screenshot of the layout of my panels. They right and bottom ones are typically set on auto hide, the top one is set so that windows can cover it. I've unhidden them all for the purpose of the screenshot. Plasma seems to have a lot of problems with multiple panels....

How many stars does your crash get in the KDE crash handler? None at all? If it has at least two, then the backtrace might be a bit useful.
