I've reproduced the bug in the latest dapper. As a matter of fact, it blocked my upgrade.
Previously, the screen flashed too quickly for a digital camera to react. Now, the freeze is slighly different, it just show GRUB. Bug #19948 is about libglademm2, I think you mistyped the number. Apparently all the information you want was given in my second message. If you need something else, please state what. -- GRUB doesn't boot https://launchpad.net/bugs/10712 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
