I've just set it up on Gmail (using VL6.0 Standard). Working fine here (with Imap, which is interesting, since I couldn't get the version of Claws-mail shipped with Salix to log into my Gmail account).
Not bad, though it doesn't seem able to pick up HTML, even though I did install the GHTML plugin. I'll have to check a bit further. Still, no crashes, and its seeing the lables I have set up in Gmail.
Ahh. Plugins are too old and don't work with the new version of Claws. Any chance of rebuilding them?
