BUG #1: When running the attached python program, I just get a blank window with a bunch of garbage in it. The program just accesses the mobile wikipedia site and tries to show a window. It's simple enough, seems like it should work. Changing the URL to google.com works without a problem. I suspect that if you can diagnose/fix this bug, then bug #2 will also be fixed. BUG #2: Accessing mobile wikipedia reliably crashes the trunk version of Exaile media player (note: I'm a primary maintainer of Exaile) using the Wikipedia plugin (see https://bugs.launchpad.net/exaile/+bug/1243712). The wikipedia plugin uses webkitgtk to render the wiki pages, and I get error messages + stack trace that looks something like this there: ** Message: console message: http://bits.wikimedia.org/en.wikipedia.org/load.php?debug=false&lang=en&modules=jquery%2Cmediawiki%2CSpinner%7Cjquery.triggerQueueCallback%2CloadingSpinner%2CmwEmbedUtil%7Cmw.MwEmbedSupport&only=scripts&skin=minerva&version=20140606T033439Z @164: Use of "name" is deprecated.
