Using Version 31.0.1700.0 (238485) on Linux. If I go to settings and clear history, no matter what is checked off, and NEVER having checked off "clear saved passwords" this is what happens. It happens randomly and unexpectedly, with no rhyme or reason. I will then check in Chromium, and all gone as well. Also random is the fact that it does not consistently ask to save passwords. Both these issues only cropped up in this version. Quite annoying to say the least.
