[GRASS-dev] Re: [grass-code I][394] scripts using g.message fail if message contains "="

[Agustin Diez Castillo]

I got errors (thousands of them) in r.tileset when trying r.in.wms  
output=elevation_meters mapserver=http://wms.jpl.nasa.gov/wms.cgi  
layers=us_ned styles=real -o
For instance
Sorry, <(142585.01085156029416302431 > 143102.29050826436668412227) *  
142585.01085156029416302431 + (143102.29050826436668412227 >> is not  
a valid parameter
/Applications/GRASS-6.3.app/Contents/Resources/scripts/r.tileset:  
line 436: 26255 Segmentation fault      g.message "$2"
In occasion even the g.message gui is launched.
