We must be getting close to Pharo 6 Release. Due to missing PharoV60.soruces file, image 60494 get a red-pane-of-death in class pane. Even though the release would bypass this by including the file, we should be more robust to the missing sources file. Hopefully this fix can make it last minute into the release...
