Yesterday morning when I fired up Chrome (Version 19.0.1084.46 on Kubuntu 11.10), it did not offer for me to restore my previous session.  There wasn't even the option to open recently closed tabs (only after I create and closed a tab did this option appear and then only with the test tab I had just closed).  I checked my history and everything appeared to be in there, but there was too many pages I had closed in there to be sure.

Bottom line all of my tabs are gone including the tabs I had pinned.  How do I restore the previous session and get them back?
