Version: (using Devel) Compiler: g++ 4.1.3 OS: Linux Installed from: Compiled sources 1. load the 'bubblemon' widget on the desktop 2. if for some reason plasma crashes, and plasma reloads the desktop it loads every other widget but not bubblemon. i.e., if i have clock, cpuinfo, bubblemon widgets loaded before plasma crashed. On plasma-desktop crash the cpuinfo, clock reappear but the bubblemon widget does not auto load after the crash
Can you try this: - Start Plasma - Load the BubbleMon widget - Quit plasma safely (run kquitapp plasma-desktop) - Restart Plasma (BubbleMon should be still there) - Now wait for a Plasma crash (or force it with "kill" and some crash signal) Plasma crashes and restarts itself Is Bubblemon still there ? Also, what KDE svn revision/branch are you using ? Thanks

hmm interesting, I tried what you mentioned Dario, but it seems that, bubblemon does load back after a plasma crash. I will try to logout and login as sometimes after a plasma crash and plasma reload, on next login bubblemon does not load, I will confirm it now.
hmm it loads now - with me forcing a kill -11 plasma-desktop and on re-login, but i am not sure if it autoloads in some instances of a plasma-desktop crash.
I remember some bug/feature about the widgets being saved only on logout/ Plasma exiting properly. So if you added a widget and plasma crashed you lost it. May be it is some kind of regression , or may be it is still there. Have you tried to add some other widget and forcing a crash ? Thanks
Dario, it might be that sometimes kdesession does not fully quit for me, so i have to force a ctrl+c/d so plasma might have not exited properly causing the bubblemon widget not being saved.
ok, it seems if kwin/plasma gets killed bubblemon does not reload on plasma reload. I just tried Current trunk details: qt-copy:959834 kdelibs:959832 kdebase:959843 with clean $HOME and '.' directories, added 'bubblemon' ran systemsettings and changed some settings, upon logout plasma crashed with sigabrt. and plasma tried to reload-itself and bang no bubblemon loaded. backtrace below: Application: Plasma Workspace (plasma-desktop), signal SIGABRT Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".

the backtrace is something else (which i'm aware of and working on), the widget-not-appearing-after-reload depends on what your fs is doing; we do save the widget settings out to disk asap. there's not much more we can do than that.
Aaron, can you point me to the bug report for the backtrace, so I can keep a track. thanks
