I have looked at this issue, I think I have an explanation:
- You start with the Git pane containing a vertical paned widget with 
all git windows in a notebook at the top and your dialog at the bottom.
- You click on the command button again
- It uses anjuta_dock_replace_command_pane to add a new dialog, 
replacing the current one.
- First this function remove the old dialog at the bottom
- This trigger the removing of the vertical pane which contains only the 
notebook now.
- The notebook is removed from the pane and added to the top git pane. 
The size of the notebook is lost in the operation, a size negotiation is 
requested but it will be done later in Glib main loop.
- You are back in anjuta_dock_replace_command_pane function and add the 
new dialog now.
- You enter gdl_dock_add_item to add the new dialog at the bottom. The 
only docking widget is the notebook, so you plan to merge it with the 
notebook at the bottom.
- But the function gdl_dock_refine_placement consider that the notebook 
is already at the bottom of the docking area (its size is not valid yet).
- So instead of adding a pane with the notebook on the top and the 
dialog at the bottom, it adds the dialog in the notebook.
-Then the size request is done and the notebook grows to fill the 
complete docking space, but it is too late your dialog is already docked 
inside the notebook.


I don't think it is really a bug in GDL. It means that you cannot change 
several GDL widgets at the same time. I think this is acceptable.

I don't know how to fix this. An easy solution is to delete the dialog 
immediately and add it later in a idle handler. A better solution would 
be to redo it as soon as the size has been renegotiated or force an 
immediate renegotiation. If you have more ideas, I'm interested.



Else, I have recompiled gtranslator and I have enable and disable 
several plugins but I haven't found an obvious missing widget. I think 
it's possible to have a widget hidden when one part of a paned widget is 
0 perhaps it can explain this issue.

Then the destination position doesn't always appear or sometimes appears 
at the wrong place. I see it in Anjuta too. But it's the only real bug 
that I have seen at the moment.
