#4900: Sugar can accidentally import WebKit1.0 (GTK2)
----------------------------+--------------------------

           Type:  defect    |      Status:  new
       Priority:  Normal    |   Milestone:  Unspecified
      Component:  Sugar     |     Version:  Unspecified
       Severity:  Blocker   |    Keywords:
Distribution/OS:  Fedora    |  Bug Status:  Unconfirmed
----------------------------+--------------------------
 On Fedora 23 Beta 1 XFCE and sugar build MODE_NONE:

 Sugar fails to start because it imports WebKit, which in turn imports
 Gtk2.  This is because it importing WebKit1.0, not WebKit3.0.

 gi warns us that we need to specify which version we want, so we need to
 add the following before the first import:

 {{{
 gi.require_version('WebKit', '3.0')
 }}}

 Irc log:

 {{{
 16:08 <ignacio> gi.RepositoryError: Requiring namespace 'Gtk' version
 '2.0', but '3.0' is already loaded
 16:08 <ignacio> wuut
 16:08 <samdroid> shell.log?
 16:08 <samdroid> what that an error?
 16:08 <ignacio> samdroid,
 16:08 <ignacio> http://paste.fedoraproject.org/277418/45371414
 16:09 <samdroid> WTF WHY DOES THE SHELL IMPORT GTK2
 16:09 <samdroid> oh webkit
 16:09 <samdroid> so we need to move to webkit2?
 16:10 <ignacio> maybe?
 16:10 <samdroid> ignacio: do the errors go away if you sed -i
 's/WebKit/WebKit2' -r src
 16:10 <samdroid> or something like that?
 16:10 <ignacio> lemme check
 16:11 <samdroid> and wtf why does this happen on fc23 and not on rawhide
 16:11 <ignacio> maybe this is important: I'm not using Gnome
 16:11 <ignacio> XFCE Spin
 16:11 <samdroid> ah
 16:11 <ignacio> the command doesnt work
 16:12 <samdroid> try
 16:12 <samdroid> find sugar/src -type f | xargs sed -i 's/WebKit/WebKit2/'
 16:14 <ignacio> samdroid, works
 16:15 <ignacio> Browse activity doesnt start
 16:15 <samdroid> so webkit1 included with the XFCE spin is GTK2
 16:15 <samdroid> wait, maybe we should use the gi version thing
 16:15 <samdroid> brb
 16:16 <ignacio> reproduced your toolbar bug btw
 16:16 <samdroid> :)
 16:17 <samdroid> just wondering, what is the WARNING output of running the
 following python statement on your machine?
 16:17 <samdroid> from gi.repository import WebKit
 16:17 <ignacio> >>> from gi.repository import WebKit
 16:17 <ignacio> __main__:1: PyGIWarning: WebKit was imported without
 specifying a version first. Use gi.require_version('WebKit', '1.0') before
 import to ensure that the right version gets loaded.
 16:17 <ignacio> >>>
 16:18 <ignacio> the background of journal is grey
 16:18 <ignacio> same with listview :P
 16:20 <samdroid> ignacio: that would be the webkit bug
 16:20 <samdroid> WebKit1,Gtk2=1.0  WebKit1,Gtk3=3.0
 16:20 <samdroid> I'll log a ticket
