I do face similar problems as is stated here. A better diagnosis is available in 1.0.0007 version of GH, however it hasn’t been released.
So I implemented a quick “fix” by overriding
Tracing.Assert form and provide a stack trace whenever it is possible. It helps you analyze what is going wrong. Just copy the two files to GH’s component folder and restart Rhino.
The add-on is thread-safe and information from different threads are shown one by one.
