wxGUI: command console with no map display open causes error

[hamish]

Hi,

if you close all map display windows so you only have the layer manager open, switch to the command console tab, and run 'v.info roads' or 'r.univar elevation.dem' etc the module runs fine but an error is printed after it:

Traceback (most recent call last):
  File ".../svn/relbr_6_4/dist.x86_64
-unknown-linux-gnu/etc/wxpython/gui_modules/goutput.py",
line 789, in OnCmdDone

display = self.parent.GetLayerTree().GetMapDisplay()
  File ".../svn/relbr_6_4/dist.x86_64
-unknown-linux-gnu/etc/wxpython/wxgui.py", line 441, in
GetLayerTree

return self.curr_page.maptree
AttributeError
:
'NoneType' object has no attribute 'maptree'

thanks, Hamish

ps- in the grey bar between the top output pane and the bottom input pane, could there be some text like "Enter command below:"? otherwise new users just see a bunch of empty white boxes and don't know where they should click. 6.4.1 had some "Cmd> " text to the left of the input box which helped as a cue.

Still the case in 6.4.svn, r52816.

Fixed in r52818, r52819, r52820, however this is a common problem which should be solved later by refactoring.
