OK, so I fixed it up to actually be correct (idx >= 0 instead of
idx < 0), which leads to an immediate:
** CRITICAL **: psppire_dict_get_variable: assertion `idx >= 0'
failed
upon PSPPIRE startup, with the following backtrace:

In other words, it's a bug in gtksheet.
I feared there might be.
I'm not enthusiastic
about fixing that, since I'm trying to replace gtksheet at the
moment, so I'm inclined to just drop this commit for now.
Sounds fine to me.
