...sometimes if it doesn't shut down nicely (as when i'm in a hurry and i just kill X) it won't show main window again, unless you wipe your $HOME/.opera directory, therefore the trick was there.
I spent five minutes looking there, and if you change variable 'Run' from 0 to 1 in operaprefs.ini, save and run opera, it will boot with startup dialog. Basically this value marks that Opera has crashed and ignites recovery mode.
And yeah, delete the $HOME/.opera/lock file if it's there.
Hope this helps fellow Opera users.
