[Pharo-dev] Pharo Launcher endless loop opening debuggers in Pharo 6.1

I ran into an annoying problem using the latest Pharo 6.1 (stable) from Pharo Launcher. I am on macOS Sierra Version 10.12.6. Steps to reproduce: 1. Open Pharo Launcher 2. Create new Pharo 6.1 (stable) image from the official distributions, named Test 3. Launch the Test image 4. Open a File Browser 5. Right click on the selected Test directory in the left file tree pane. 6. Debuggers start opening on KeyNotFound: key #arg4 not found in Dictionary 7. Image hangs Interestingly the problem does not happen if I create the image using „curl get.pharo.org | bash“ and start it with „./pharo-ui Pharo.image“ although About Pharo shows the same information: Pharo 6.0 Latest update: #60523 Can someone please confirm the bug?
