Comment 1 Andrea Diamantini 2011-03-19 08:44:52 UTC 
With my first eye, it seems a rekonq problem. Targetting 0.7, thanks for the report...
Comment 2 Andrea Diamantini 2011-03-19 09:42:34 UTC 
Git commit a309167dc747072830ad47b979c926e9083e6f63 by Andrea Diamantini.
Committed on 19/03/2011 at 09:44.
Pushed by adjam into branch 'master'.

Check if mainWindow  and currentab really exist before using in bookmarksprovider.
In fact now this is NOT automagically ensured there (as in any non widget rekonq class)

BUG:268838
