Here is the backtrace extracted from the crash file:

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

The issue is there:

  void FilePicker::Done(const std::vector<content::FileChooserFileInfo>& files,
                        content::FileChooserParams::Mode permissions) {
    render_view_host_->FilesSelectedInChooser(files, permissions);

where render_view_host_ is null.
