[GRASS-dev] gis.m: cannot get profile from profile tool

[Patton, Eric]

Hi guys,

I tried the porfiling tool with July 31 cvs, and I can't get it to work. The
y-axis gets assigned correct values for the profile I've drawn, but no lines
get drawn in the profile window. A tcltk window reports "Error: can't read
"cumdist": no such variable"

You can view the output on my ftp site:  

ftp://agc.bio.ns.ca/outgoing/Patton/Grass/Bug%20Reports/

Yes, as you can see in the screenshot, it says in the bottom left: 
"Profile for srtm_be".

I understand that, but I still don't get a profile. Actually, I 
sometimes do not even get the straight blue line you see in the 
screenshot (http://moritz.homelinux.org/grass/gism_profile.png), just an

empty graph.

The min and max of the heights on the y axis seem correct, though.
