It is about Debian based distros. 8.4 used to work fine for me in
Mandrake with NVIZ. On Ubuntu Hoary I had problems - 8.3 was required
for NVIZ to run. Same as for other users (see grasslist archives). I
haven't tried 8.4 with NVIZ on my current Ubuntu Breezy yet being
aware of problems in Ubuntu Hoary and Debian.

There are reports in bugtracker regarding infinite loops in tcl/tk

I used to get this error from time to time on Mandrake using tcl/tk
8.4 with different commands. And there are at least 2 reports more of
this bug by other users in grasslist archives (both for v.in.ogr) and in
grass5 archive: 1 for v.in.ogr and 1 r.flow. So it seems pretty common.

Interestingly, since I switched to Ubuntu and tcl/tk 8.3, as it is
required for a Debian fork to be able to run NVIZ, I've never had this
issue anymore. This could be a coincidence, but it might seem that 8.3
is less prone to this problem than 8.4. Can somebody confirm or deny?
