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 svn info qt-copy: 942255 kdelibs:956023 kdebase:956038 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:

I hope the bt was useful
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 |
