Version: (using KDE 4.0.98) Installed from: Ubuntu Packages OS: Linux If I add a panel and open up the +Widgit, then remove the panel and add the widgit, plasma will crash. Basically when adding a widgit to a panel that doesnt exist, plama will crash and take my Kmenu from my main panel with it. I then have to readd that after the crash.
Please read the following page and provide a useful backtrace for this crash : http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports Also mention which widget you try to add.
I tried adding multiple widgets including the Kmenu and Clock.
I should also note that I installed to virtualbox, with guest addons with Kubuntu 8.04 Remix.
SVN commit 833976 by aseigo: watch for containment destruction; for people who like torturing plasma in weird nd wonderful ways BUG:166824 M +15 -0 appletbrowser.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=833976
very frustrating for newbies, when the boss checks in the fix, just when I had my almost identical patch ready ;-) Anyway - your patch introduces a crash by leaving the containment as null pointer. You trigger it by clicking the Add Widget Button after the panel is removed. Two solutions seem possible: -deactivate the Add Widget Button (you can then still drag an applet to another containment) -destroy the AppletBrowser completely (This is what I did even though it is kinda hackish, because only the AppletBrowserWidget keeps a pointer to the containment and I had to assume that destroying its parent would do the trick, this wouldn't work when that widget is embedded deeper or elsewhere) I like the 2nd approach more because deactivating the button would mean finding all the paths, where that widget is reused with another containment and activating the button then again.
"You trigger it by clicking the Add Widget Button after the panel is removed." incorrect: void AppletBrowserWidget::addApplet() { if (!d->containment) { return; }
sry, my analysis was wrong - the connection is never made: QObject::connect: No such slot Plasma::AppletBrowserWidget::containmentDestroyed() because the slot is defined in the AppletBrowserWidgetPrivate, this causes the containment not to be set to 0 even if this connection is made correctly, wouldn't that mean that the add Widget button is just going to do nothing in that case? Should be grayed out then I guess.
> the connection is never made your svn checkout is not up to date =) > wouldn't that mean that the add Widget button is just going > to do nothing in that case? currently, yes. > Should be grayed out then I guess. what i think would make even more sense (at least for the plasma workspace) would be to re-associate itself with the containment that is associated with the screen the dialog is on. in a more generic fashion, having a "default containment for this browser" is what we'd want.
Created attachment 26242 [details] Crash report This is a crash report. Version 4.00.98 (KDE 4.0.98 (4.1 RC1))
Also, when I logout and log back in I find a panel behind my main panel that extends to touch the right side(my main panel seems to be slightly stunted and only progresses 4/5 the way across the screen). When I remove this panel kde crashes.
Created attachment 26243 [details] After I logout and log back in, and try to remove the extra panel, KDE crashes.
I still seem to encounter this problem with KDE 4.1 final.
Brad: your crash is not the same as this bug. please open a new bug, but only after making doubly sure all your plasma applets are up to date. the backtrace you provided is not completely useful (see link at the end of this comment), but it looks a lot like a binary incompatibility problem due to stale applets (perhaps from a beta or other-pre-release) hanging around. http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports
