Hi Profs. Flatt and Findler, Thanks for the prompt response! Long story short, the problem seems to have been on Ubuntu's side, and was fixed in today's update. I was using a fairly vanilla Ubuntu 11.04 (64-bit); the problem was that upon launching DrRacket (either from the terminal or through Alt+F2) the whole system would freeze, precluding any possibility of stack traces &c. (The Racket REPL worked well.) There was an update to Ubuntu's Unity interface about 9 hours ago [1], and now DrRacket launches fine and flawlessly for me. There's no specific mention of DrRacket in the changelog, but Bug #754063 [2] seems similar: the whole system would sometimes freeze under certain conditions. I haven't investigated further, but it seems that Ubuntu was at least partly to blame. Thanks again!
