I created separate workspaces for different tasks and moved all my open tabs into the appropriate workspace.

Then when the time came to actually open one of my carefully crafted workspaces opera crashed and removed all the tabs in my "default" workspace.

I am unable to open any other workspace but the "default" one, and all those tabs I organized seems like they are gone.

I know it is probably because I'm silly enough to be using the developer version as my daily driver, but I'm just spoiled in that it usually isn't a problem. And workspaces has been around for so long I kind of didn't expect it to be such a disaster...
