Using the attached test case (fixed up so it compiles without warnings), I was able to reproduce the bug inside the gtk+2.0-2.10.6/upstream/tarballs/gtk+-2.10.6/tests source tree.
The package in edgy-proposed fixes this bug without causing regressions. Approved to go into edgy-updates today. ** Attachment added: "gtk+2.0-2.10.6/upstream/tarballs/gtk+-2.10.6/tests/67917.c" http://librarian.launchpad.net/5214817/67917.c ** Tags added: verification-done -- Bug #61835 it's happening again, no grid-lines https://launchpad.net/bugs/67917 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
