Subject: v.support problem?

Platform: Linux/Intel
Linux distro: RedHat
linux cpu: Intel (i486, i586, pentium ...)
Xwindows manager: GNOME
grass downloaded at: Hannover site  (??)
grass binary for platform: I compiled the sources myself
grass sources source: no, I got a source code package from the server, GRASS5.0.0pre2
c compiler name: gcc

I want to perform,import the map from ARC/INFO e00 format data
and generate HTML clickable map contents.And performed the shell
as [list 1]. But 9 of 152 polygon datas cannot import into GRASS 
vector file. other polygon data can be imported and correct HTML 
contents are generated. 
In this shell,the command v.support prints 9 line error messages 
as [list 2].

Is this a GRASS bug?
