I found this happening to me regularly and eventually found the culprit. It happens when another Chrome window is opened (clicking a link on an email?) and not closed before shutting down/logging out.
Because this window uses the same profile as the main Chrome instance it will overwrite any record of the open tabs from that instance.
Basically the settings remembered are those of the last Chrome instance to be closed.

I'm not sure what to suggest in that case. I've played around with my chrome settings a bit to try to duplicate the problem, without success. What do you have selected in settings -> On-startup?

I just realized that Chrome was filling its disk space with cached data.
I have Chrome configuration in a 400MB TrueCrypt file system to easily move it around between machines. When that file system is full, it is not able to write tab information. That explains the problem.
I just emptyed the cache and lots of space were freed.
There seems to be now way to limit the cache disk space in Chrome like there is in Firefox.

Thanks but this is not exactly the ideal solution. It would be better an option on the settings page, so we do not have to start Chrome manually with command line switches.

Manuel, it's simple. If you're starting Chrome by clicking on a desktop icon just right-click on it and select 'properties'. One of the tabs will have a command field with something like 'opt/google/chrome/google-chrome %U' in it. Just edit this to include the command line switches. It's similar if you're starting it from a taskbar launcher icon.
It gets only slightly more complicated if you're starting it from the menu. Somewhere among all the menu items you'll find one like 'main menu' (the menu editor) in this applciation just find the chrome entry and edit it as above.
