I recently had the same issue - I have an old Samsung Galaxy S with Android 2.3.6. I think somehow an app got updated when I was on WiFi, but I didn't know what it was. I noticed a "sync" icon appeared and would not go away. I finally realized I could go to Settings → Applications → Battery Use, and find out that YouTube was the culprit. Then I ...
At least for me, it was actually the device password - used to unlock the phone. So basically it asks for the device password when you try to add a new Google account for some reason. I formatted my phone thinking something else was the issue - but if you enter the device password, it then asks for the account name as normal.
Not enough rep to comment... but I had this exact issue on my stock Nexus 7 and the only solution that worked was a factory reset. I also have a Nexus 4 running Chroma and haven't seen issues with either the Jan or March build. If nothing else works, you might try a full wipe and installing the ROM / kernel again.
Factory reset will resolve this issue! To get to that option though you have to be in recovery mode. To boot to recovery mode press the power button and volume up button simultaneously! And then you will get this screen: Then just reset to factory version and it should work!
Did you try booting into safe mode once (powerbutton then long tap power off). After starting in safemode, restart into normal mode. Had the issue, and this worked for me.
Instead of a factory reset and install everything again, you can download a home launcher from appstore! Set your new home launcher as default then uninstall quick mode(sucks bigtime)... I like my phones new look, i even got rid of the left page on the homescreen. :-)
Issue resolved by running rm -r from the Custom Recovery cmd. I'll create the folder again and see if the problem reoccurs, hopefully it was just a 'random' glitch. (I should probably mention that I use a nightly version of CM12.1, not a stable ROM).
Sorry for the trouble. I'm the writer of that fix. Well, I was able to get it right on Nexus 5, Unite 2, Galaxy S5, LG G2, LG G3 and MOTO G as well. So, if you've come across a different problem try doing a factory reset. And, keep a backup of your data before formatting it.
