Bug 201088

Version:            (using KDE 4.2.4)
Compiler:          i686-pc-linux-gnu-4.3.2 
OS:                Linux
Installed from:    Gentoo Packages

Remark: Although I'll write a lot about KNotes below, I think the bug lies within KDE/Plasma.

I'm using KNotes and multiple desktops. For each note, knotes stores on which desktop and at which position that note is placed. I also use KDEs session management, i.e. during KDE shutdown, it remembers what applications were open and where their windows were.

So, for the knotes windows, their position is saved twice; on the one side by knotes itself, on the other side by KDEs session management. This has never been a problem so far until today, as normally both positions should be identical, so I don't care who places the notes, as long as their position is right.

When logging in today, the notes' positions were mixed up. Lets say, I have three notes, A, B, and C. At the original position of note A there was no window. At position of note B, there was note A. At position of C there was B. You get the point.

Things I did afterwards:
1. Kill X-Server (Ctrl-Alt-Backspace) so that neither KDE nor KNotes would write back any changes I made to window positions etc. Logged in again, exact same behavior as described above.
2. Had a look into KNotes stored positions. No problem here, everything right, no corrupt entries etc, saved positions were right, too.
3. As Knotes saves the notes positions during shutdown and they were wrong at the moment (described behavior), i did a 'killall -9 knotes'. After starting knotes again (without restarting KDE), it placed the notes at the right positions.

The only explanation I can come up with is that KDE stored session information wrong during the last shutdown and thus screwed up windows positions of that programm during the next startup, although I can reproduce this. Also, I think there is some kind of conflict with window position management. Although it is ok to manage windows positions for programs that do not do that themselves, it conflicts with other programs that do.
