[Rhythmbox-devel] merge_source_ui_cb and SearchBar GtkAction

[Peter <rhythmbox-devel maubp freeserve co uk>]

Hi all,

I'm trying to use RB from source on Ubuntu Lucid. I've got the latest code
from git and while it configures and builds, it won't run...

Note I've installed the current libdmapsharing (from git) under my home
directory as I want to use the DAAP plugin.

$ export LD_LIBRARY_PATH="$HOME/lib:$LD_LIBRARY_PATH"
$ export LD_RUN_PATH="$HOME/lib:$LD_RUN_PATH"
$ export PKG_CONFIG_PATH="$HOME/lib/pkgconfig"
$ ./autogen.sh --prefix=$HOME --enable-daap
...
configure: Rhythmbox was configured with the following options:
configure: ** Tree database is enabled
configure: ** Multimedia keys support is enabled
configure: ** MusicBrainz support is enabled (using libmusicbrainz)
configure: ** iPod integration enabled
configure: ** MTP integration enabled
configure: ** CD burning support enabled (using Brasero)
configure: ** DAAP (music sharing) support is enabled
configure: ** libnotify support is enabled
configure: ** GUdev support enabled
configure: ** Python plugin support enabled
configure:    Vala plugin support disabled
configure: ** gnome-keyring support enabled
configure: ** FM radio support enabled
configure: ** iTunes detection browser plugin (for podcasts) enabled
configure:    Last.fm support disabled
configure: End options

$ make
...


$ cp data/rhythmbox.desktop $HOME/share/applications
(to avoid RB complaining about not finding this file)

$ shell/rhythmbox

I thought I should try running this in the debugger - not sure if this
is the best
way of doing it but...

Looking at the merge_source_ui_cb function at line 408 of
shell/rb-source-header.c
it is failing to find the search bar widget. Any suggestions? I'm
wondering if I need
to update my libgtk ... one option might be to update the whole machine from
Ubuntu Lucid to Maverick.

Thanks,

Peter
