 Hello,

 I have wxgui crashing during edit a vector file in GRASS wxgui. Displaying
 / browsing the map is ok.

 During editing, as I pan I have this messages in the console:

 Traceback (most recent call last):
   File "/usr/lib/grass72/gui/wxpython/mapwin/buffered.py", line 585, in
 OnPaint
     self.pdcVector.DrawToDCClipped(gcdc, rgn)
   File "/usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/_gdi.py", line
 7696, in DrawToDCClipped
     return _gdi_.PseudoDC_DrawToDCClipped(*args, **kwargs)
 wx._core.PyAssertionError: C++ assertion "n > 1" failed at
 ../src/common/graphcmn.cpp(742) in StrokeLines():

 Then GUI crashes as I end the editing process (it successfully saves the
 vector file).

 python-wxgtk3.0 3.0.2.0+dfsg-5
 GRASS: 7.2.1-3
