Version: 4.1.85 (using Devel) OS: Linux Installed from: Compiled sources When Widget Browser is open, a Plasmoids is selected and 'Add Widget' is pressed (drag n drop works fine) three actions can appear: 1. Nothing happens 2. Plasmoid will be created on desktop 3. Plasma crashes (it DOES NOT restart) and the desktop is black. Via alt-tab you can reach other apps and restart plasma via krunner. Working on 4.2b2 provided by Kubuntu Experimental PPA.

can you install the debug package(s) for kdebase and replicate this to get a full backtrace? thanks =)
(In reply to comment #1) > can you install the debug package(s) for kdebase and replicate this to get a > full backtrace? thanks =) > Can't reproduce it right now. Very strange.
hmm, this looks like a backtrace from a task manager bug, seems strange the add widget dialog is involved at all.. what widget did you add when the crash occurred?
It was xeyes. Might be, that this was a mystic triangle of circumstances ;)
I can't reproduce here. Could you tell us if you where doing this with a specific widget? i tested with calendar and comic
SVN commit 898961 by mart: Arbitrary limit the number of attempts. Better a non optimal position than a frozen plasma, wonder if it's related with 178076 CCBUG:178076 M +1 -1 itemspace.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=898961
what i did get with a very crowded desktop was a freeze without crash, i suppose it's the nothing happens part, that now it's fixed. the crash i really don't think it's related
bug 179321 seems to have the same but more complete backtrace in 4.2b2
*** Bug 179321 has been marked as a duplicate of this bug. ***
Hi! Someone pointed me out that my Bug looks similar to this one, so I post my report here... Plasma crashes on logout in kde4.2.0-1. It's unreproducible but I got a backtrace. The machine is a Debian Sid/experimentl amd64 Laptop with an Nvidia nvs 140 running binary only driver from nvidia on kernel 2.6.29-rc3.

hm. this is actually a crash in the tasks-widget. I have seen the same backtrace when closing plasma.
I've got a similar crash, same methods but different line numbers. I'm using KDE 4.2.00 "release 83.1" from openSUSE_11.0, KDE:KDE4:Factory:Desktop.

similarly using latest 4.2 RPMs for openSUSE 11.1... debug not installed BTW if I install debug package does it get in the way of normal usage (e.g., speed, performance)?

@Gerry: your crash is unrelated to this. Please file a new bug report and include information about your installation and your weather plasmoid configuration (is crashing in the weather info fetching engine)
@Dario: On searching before reporting, it looks like a potential duplicate of 182799 which has an upstream fix
Bug 183013 seems to be this bug, it has steps to reproduce

I just got this crash. I was editing the panel and started moving the taskbar by accident. I pressed Esc while dragging it, hoping it would cancel the change. Instead, taskbar disappeared completely. I opened the "add widget" dialog - but it showed that the taskbar was already added. I added it again, then decided it would be better to remove the old one first. But when I tried removing it, it crashed.

Bear with me on this one. The following is a distillation of common factors. Running latest openSUSE updates 11.1/KDE4.2 Log on yesterday - try to launch any application from bottom panel (e.g. Kontact, Konqueror) crashes plasma, no backtrace, after a while plasma restarts, all widgets working, no panel, have to use cntl-alt-bksp to continue (repeatable) (deleting the plasma config settings in .kde4 did not improve things) All the applications work in KDE3 Check software updates (I do not have unstable repo but do have factory) add a few KDE4 bits and pieces, no particular reason Restart KDE4 - normal working restored Log in and out a few times (to test if ,kde4 settings are being written) Shutdown Today much the same thing has happened Same sequence, seemingly cured by adding a few KDE4 bits and pieces
Not quite believing my own report (#21) I've just shutdown and restarted the system and I am writing this from within KDE3 as KDE4 is crashing as described. Hopefully there are some KDE4 updates on the repos
Gerry: your crash is in the weather engine. not the same at all as this report. please open a new report if it continues for you.
