Sorry for not testing it earlier, so I did that switch now and have:

d->m_cfg = KSharedConfig::openConfig( d->developerTempFile );
d->m_cfg->addConfigSources( QStringList() << d->projectTempFile );

KConfigGroup projectGroup( d->m_cfg, "Project" );

QString managerSetting = projectGroup.readEntry( "Manager", "KDevGenericManager" );

And projectTempFile contains the Project group with an entry for
"Manager" thats not "KDevGenericManager"

When I now start KDevelop and let it load the project, I get a happily
cycling KDevelop at 90% CPU, because its using the KDevGenericManager
and not the Manager plugin that is stated in the projectTempFile.

Additionally to that I just found out that, using the original way I
posted, i.e. having the config created from projectTempFile and adding
developerTempFile (though this time the code is using KConfigSkeleton to
create the KConfig object), writing sometimes writes to the right file.
As far as I can see this happens when the group that should be written
to is already in the developerTempFile, when the group either doesn't
exist at all or exists in the projectTempFile the writing goes to the

So there might be not just 1 bug around.


You will have long and healthy life.
