I see this also on BQ M10 including on OTA-12 current rc-proposed. There is no reliable to way to reproduce that I can find, but if I open multiple tabs and then close 1 of them there is a chance that it closes the whole browser. I don't think the browser is crashing, because I don't see crash reports listed that correspond.
