When you say it "rarely works" when run as a GUI app (vs console), it makes me think that there's probably a race condition going on, and the extra context switching that takes place in GUI mode makes it more likely. I haven't tried it in D, but you may be able use Application Verifier with your app to add checks for lock contention. Without more information about the way your threads are synchronized it's hard to say for sure though.
The codebase is a reasonable size so too big (and proprietary) to share.
It's always run with a GUI (GTKD), it's just the difference in linking so launching (a)GUI + attached console for stdout.writeln vs. (b)just the GUI window. There's nothing I'd expect to cause races or deadlocks.
