Here's a rather odd problem I'm having. Whenever I open the dash and type into it, Chromium opens up and opens an "about:blank" tab for just about every letter I write into the dash. Why is it doing this and how do I stop it from doing this?
The workaround is to turn "Include online search results" option off.
I believe found a fix.
If you have "Online Accounts" authorized for Ubuntu/unity system (the gear icon in the upper right -> System Settings -> Online Accounts) and there is a access issue (Shows a red gear icon and throws a warning on boot) then this bug happens.
The fix is to re-authorize your existing accounts (Perhaps it occurred because I had changed my google password, and so they became unauthorized?) which can be done from
System Settings -> Online Accounts. Correct any errors listed.
In any case, re-authorizing my Google accounts seems to have fixed the problem for me. Hope this helps.
