Basically it enters infinite loop and after passing a certain commit it starts all over again and creates duplicates. If you want to recreate the issue - try to set this https://github.com/godotengine/godot as subversion repository for a project, here highest changeset will be 1159, which is this one https://github.com/godotengine/godot/commit/88d64e7735a9b1ba99b3b6a785b394bccda8ea2d after this one it starts from the beginning. Please fix it, as it would be nice to see recent commits inside activity tab. But first need to be able to clone the whole repository somehow. Begin of the deletion
End of the deletion
