golang.github.io/dep crashes with tabs_are_windows set

[The-Compiler]

./.tox/py36-pyqt510/bin/python3 -m qutebrowser --temp-basedir -s tabs.tabs_are_windows true golang.github.io/dep

crashes as soon as the mouse is moved with:

17:21:12 WARNING  qt         Unknown module:none:0 The X11 connection broke (error 4). Did the X11 server die?

but only when tabs.tabs_are_windows = true is set... 😕

Seems to happen with any Qt version, and with both QtWebKit and QtWebEngine.

This seems to happen when setting the window icon:

    @pyqtSlot(browsertab.AbstractTab, QIcon)
    def on_icon_changed(self, tab, icon):
        # [...]
        if config.val.tabs.tabs_are_windows:
            self.widget.window().setWindowIcon(icon)

The page has https://golang.github.io/dep/docs/assets/DigbyScene2Flat.png set as favicon, which is a 2869x2921px PNG. I'm guessing X doesn't like such big icons...

The solution I use now is to set tabs_are_windows = false whenever I encounter this issue.
Since this does not seem to be a qutebrowser issue I'm gonna stay this for now.

Thanks for the quick response
