Comment 4 for bug 254912

I'm marking this as invalid. I haven't been able to reproduce under real-world circumstances. We did have Nicolas see a reproduction by updating from a 8/15 build, but I couldn't duplicate it.

You can test the responsiveness of the icon by 'sudo touch /var/run/reboot-required; sudo touch /var/lib/update-notifier/dpkg-run-stamp' and seeing how long it takes to notice. Doing this seems to take a good chunk of time for it to notice (like ~10s). But it eventually comes up. Perhaps that's all that happened on the original report (and Nicolas's repro)? But I still haven't seen a delay when actually updating.

If this can be reproduced after waiting a good long while, please reopen. And if so, please report the timestamps of the above two files (/var/run/reboot-required and /var/lib/update-notifier/dpkg-run-stamp). Maybe I'm missing a piece of the puzzle.
