Comment 4 for bug 1702407

Sorry I didn't tell the whole story...

close chromium
$ sudo apt-get purge chromium
rename ~/.config/chromium (which remained after purge, not sure if it should?)
reboot
$ sudo apt-get install chromium
copy old Bookmarks to new ~/.config/chromium/Default/

Before this, I tried upgrading a VM with 16.04.1 to the latest version of chromium, which worked perfectly, and still worked after dist-upgrade to 16.04.2 - but the VM (and certainly its version of chromium) was pretty much otherwise unused, so I wondered aloud about potential causes.

I don't see why a reboot should make a difference but I hope that works for you - mine is now working normally again. I should have explained more fully before.
