A startup crash that wore two disguises

If you left the editor open with a draft when you last used the app, the next startup could crash quietly: the app tried to restore your draft before one of its writing tools -- the piece that turns rich text into markdown -- was ready. Everything after the crash never ran, and the damage showed up as two seemingly unrelated bugs: your name missing from the menu bar, and the Publish button refusing to enable while you typed in the body of a post (typing in the title, which takes a different path, still worked -- which is why the bug seemed to be about titles). It surfaced during the demo.rss.chat database migration this morning, was reproducible one minute and gone the next, and the last piece of the puzzle was browser caching: the fix was live but browsers kept running the old code until the cache-buster on the script address changed. Fixed by DW: the converter now starts first thing, and the script address was bumped so every browser picks up the cure. (Client v0.6.11.)
