Hi, while Komodo is closed, please go to your Komodo profile folder (~/.komodoide/10.0/) and navigate to the codeintel/ directory. Move the "symbols.db" file to "symbols.db.bak". Then run Komodo again and see if that fixes anything.
It appears the "symbols.db" file is locked for whatever reason. Renaming it forces Komodo to create a new one that hopefully will not be locked. If all is good, you can remove the ".bak" version.
