Description Eike Hein 2012-03-07 23:58:20 UTC 
When creating a new, empty session in KDevelop and then opening the first project in it, SessionPrettyContents in sessionrc is set to "(no projects)". This writeout only occurs when the first project is opened, and is obviously not actually true at this point: We did just add a project, after all.

Writing this key is done by Session::updateDescription(), which loops over the project files listed in '[General Options]Open Projects' in the same file. My guess is that there's a race condition causing updateDescription() to be called before 'Open Projects' has been written.

When closing the session/app, the method runs again and the correct SessionPrettyContents is written.

The reason we need this to done correctly the first time is for the data engine that's monitoring the session dirs and feeding data to the KDevelop Sessions plasmoid: With the current behavior, the new session pops up as "(no projects)" in the session list. That said, the same is probably true for kdevelop --ps in this situation.

It's odd though, ProjectController::projectImportingFinished() calls saveListOfOpenedProjects() before emitting the projectOpened() signal that causes SessionController::updateSessionDescriptions() to run, and saveListOfOpenedProjects() does take care to sync() the KConfig group. In theory the sequence is correct, yet for some reason Session::updateDescription() winds up with an empty project list.
