Review request for KDE Frameworks.


Bugs: 343735
    https://bugs.kde.org/show_bug.cgi?id=343735


Repository: kio


Description
-------

This is an attempt to fix a bug that seems quite difficult to reproduce, but definitely happens
It seems there is a weird race condition linked to the sync of the two files
.local/share/user-places.xbel
.local/share/kfileplaces/bookmarks.xml
causing the bug
https://bugs.kde.org/show_bug.cgi?id=343735
all processes that are listening for changes in the bookmark manager will try to sync their bookmarks with the shared ones (user-places.xbel) and depending what process arrives first, some bookmarks may be lost


if this is ok, it will have to go in kdelibs4 (since distributions will support kde4 apps for a long time still)
as well as (ouch) dolphin both 4 and 5, since it forks KFilePlacesModel
