Thanks, Guillame.
And i have to apologize because of the simplyfied example.
What i really wanted to do is get the first point of a path
and display it via a message. (gimp-path-get-points which returns
INT32, INT32, INT32, FLOATARRAY).
example in fu-console:
(gimp-path-get-points 1 "selection_to_path")
(1 1 135 #(275 98 1 281 94 2 286 95 2 293 94 1 308 92 2 337 93 2 349
87 1 348 85 2 348 84 2 346 83 1 341 80 2 323 76 2 317 75 1 317 75 2
233 61 2 233 61 1 224 60 2 208 56 2 201 61 1 191 68 2 191 80 2 191 91
1 191 107 2 182 122 2 182 138 1 182 143 2 182 148 2 184 153 1 189 170
2 207 178 2 223 184 1 260 198 2 310 202 2 345 182 1 350 179 2 358 174
2 362 169 1 371 159 2 380 140 2 369 128 1 362 121 2 344 116 2 335 113
1 335 113 2 275 98 2))

For a first test i wanted to display the first INT32 returned value in
the message. So the "car" is a relict of that test which crashes in
the same way.

Cheers
