GList and segmentation fault

[Mattias Persson <matper-8 student luth se>]

Hi!
Can anyone tell me what is wrong with this:
I create a GList and add something in it:

GList * files = NULL;
//nextfile is a string
files = g_list_append(files, nextfile); 

later on when a GtkList is created I try to add the 
GList to it:

gtk_list_append_items(list1, files);

but that gives me a segmentation fault.

Can anyone from this information tell me what is going 
wrong?

Thx
/Mattias
