wxgui: display labels doesn't work

[hamish]

as reported on grass-user:

> I find the label layer I generated with v.label. 
> Here I get this error message:
> 
> --%<--
> Error
> Map <> not found.
> --%<--

spearfish example:

add grid or labels overlay button -> add labels -> name of label file -> rush.lbl -> [ok]

then you get the error shown above.

see OnAddLabels() in wxgui.py and gui_modules/wxgui_utils.py

Slightly related, the order of v.label and v.label.sa (what does the 'sa' stand for?) appear to be mixed up. Selecting 'Create optimally placed labels' launches v.label, and vice-versa.

still in the latest SVN? I though we fixed that some months ago.

utils.py patch

The attached patch (wxgui_dlabels.patch) fixes this issue for me in the latest 7.0 svn. I'm not very familiar with the specifics of the wxGUI so this may be just a work around rather then a proper fix.

The patch proposed in this ticket works well for me. Any reasons not to apply it ?
