Hello, I saw your bug, and a new release of cyclograph (1.9.0) got rid of the deprecated webkit dependency. Nevertheless I cannot assure that the package will be uploaded in testing before the autoremoval occurs. Since this issue affects only one of the binaries provided, is there any way to just remove the gtk UI (cyclograph-gtk3) and leave the main package in testing? Another solution could be a nmu since I've already pushed the packaging of the latest version of the packag on the pkg-runnign-devel git repository, but the debian maintainers in the group are probably busy to upload it.
Please let me know if any of these solutions can cope with the bug. -- Federico
