 When I close the wx monitor after displaying a raster and trying to
 display a raster legend, or only after displaying a raster or vector map,
 I get:

 {{{
 wx._core.wxAssertionError: C++ assertion "GetEventHandler() == this"
 failed at ../src/common/wincmn.cpp(477) in ~wxWindowBase(): any pushed
 event handlers must have been removed

 The above exception was the direct cause of the following exception:

 Traceback (most recent call last):
   File "/home/veroandreo/software/grass78_git/dist.x86_64-pc-linux-
 gnu/gui/wxpython/mapdisp/main.py", line 565, in OnExit
     for f in six.itervalues(monFile):
   File "/usr/lib/python3.7/site-packages/six.py", line 584, in itervalues
     return iter(d.values(**kw))
 SystemError: <built-in method values of dict object at 0x7f730b192a00>
 returned a result with an error set
 }}}
