 gtk_container_add (GTK_CONTAINER (listbox), list);

(See docs/Changes-1.2.txt)

These are most likely produced by some bugs we are working on fixing
for GTK+-1.2.5

Not sure where these are coming from. The timeout / idle
code looks like it should work. 

(Though note that the tags are defined as being guints with
 valid values strictly greater than zero, so you should generally
 use 0 as a flag value for an unset timeout, not -1)

To track this down, you can run your program under a 
debugger with the --g-fatal-warnings command line option.
