#3324: Better error message if v.in.wfs fails during networking
-------------------------+-------------------------
 Reporter:  marisn       |      Owner:  grass-dev@…
     Type:  enhancement  |     Status:  new
 Priority:  minor        |  Milestone:  7.4.0
Component:  Vector       |    Version:  svn-trunk
 Keywords:  v.in.wfs     |        CPU:  Unspecified
 Platform:  Unspecified  |
-------------------------+-------------------------
 An example from #1586:

 {{{
 v.in.wfs url=http://www2.dmsolutions.ca/cgi-bin/mswfs_gmap output=parks
 }}}
 will fail as there is no DNS entry for the FQDN. Still such error is not
 reported by an error message but by a traceback:

 {{{

 }}}

 Traceback should be replaced with more meaningfull error message.
