Re: GTKTreeView Question. (Core Dump on GList append) - Strange

[Harring Figueiredo <harringf yahoo com>]

   If I change the GList to a GSList, everythigng works as expected, i.e, no
coredump.
   Does GList has some initialization routines that I did not see on the docs
that is different froma GSList ? (likely improbable, but...).
