xfce_panel_plugin_set_expand() doesn't work as expected for external plugins. Please consider the 2 patches attached to this bug. Both patches are for the testplugin in xfce4-panel sources. The first patch enables installation of the plugin and sets the expand capability of the plugin to TRUE. The second patch does the same thing as the first one plus transforms the testplugin into an internal plugin instead of external. Don't apply the second patch over the first one; both should be applied to current trunk. Needs to reautogen after the patches are applied. Consider the following scenario: 2 panels, one at the bottom and the other at top, both centered and fullwidth (this is my setup with which I've done the tests). Apply first patch, add testplugin to one of the panels and move it to the other panel. It won't expand anymore, neither if moved back to the original panel. Apply second patch, add testplugin to one of the panels and move it to the other panel. It expands normally, as expected.

Thanks, I need to have a look at that. My guess is that it is some sort of race condition or timing issue with the plug/socket communication. XEMBED is such a pain... :(
