Comment 2 for bug 1594331

I can confirm this bug. Using xreader to display the pdf output of RStudio it will frequently crash, when the file is changed (by R / Rstudio).

When run from CLI I get:

(xreader:21665): Gtk-CRITICAL **: gtk_widget_get_parent: assertion 'GTK_IS_WIDGET (widget)' failed

(xreader:21665): GLib-GObject-WARNING **: invalid unclassed pointer in cast to 'EvWebView'
