Unfortunately the problem is that Guile optimizes away whole chunks of code, and thus debugging information is not as good as it could be, and if you set traps they might be optimized out too. My understanding is that this could be made better, but could use a champion.
(The other trick is to turn off the optimizations when debugging, which is sometimes what I do.)
Cider has worked the best for me. I've used Cursive in Intellij but I ran into a lot of issues where it would not trip the debugger for some reason where Cider worked fine.
