[gnome-db] valgrind invalid read

Hi Vivien,

while running Anjuta on valgrind we discovered a strange thing happening 
on libgda, gda-holder.c : 1044

#
==14546== ERROR SUMMARY: 172533 errors from 188 contexts (suppressed:

The question is: can the current_val have some uninitialized 
value/memory that causes the warning?
The type of the value is a string, so maybe there's a dangling pointer?

thanks and regards,
Massimo
