Public bug reported:

In the latest pre-release of cairo (1.11.2), a symbol which the clock
plugin uses appears to have been removed.  Instead of gracefully failing
to load the plugin, cairo-dock segfaults.  Unfortunately, cairo-dock-
plugins doesn't allow for disabling the clock plugin from being built or
being loaded, thus the only workaround is to disable plugins altogether,
which isn't ideal.


This is spat out when cairo-dock is started from a terminal:
while opening module '/usr/lib64/cairo-dock/libcd-clock.so' : (/usr/lib64/cairo-dock/libcd-clock.so: undefined symbol: cairo_dock_reload_current_module_widget_full)
Segmentation fault

Further, when attempting to build cairo-dock, this is spat out:
Linking C executable cairo-dock
CMakeFiles/cairo-dock.dir/cairo-dock-menu.c.o: In function `_cairo_dock_launch_new':
cairo-dock-menu.c:(.text+0x31): undefined reference to `myContainersMgr'
CMakeFiles/cairo-dock.dir/cairo-dock-menu.c.o: In function `_add_desktops_entry':
cairo-dock-menu.c:(.text+0x141): undefined reference to `g_desktopGeometry'

CMakeFiles/cairo-dock.dir/cairo-dock-menu.c.o: In function `_cairo_dock_move_appli_to_desktop':
. . . and so on.

I presume that this is a problem in the plug-ins package as well as
core, so I'm not sure whether there should be a bug for both(?).  The
problem was already present in cairo revision b5152:
http://cgit.freedesktop.org/cairo/commit/?id=b5152

A haphazard guess: Perhaps cairo-dock was using private cairo API which
was removed whence: http://cgit.freedesktop.org/cairo/commit/?id=ff9e9
