Good luck, I can add one bit, the segfault must have come as I closed Geany since it didn't appear to crash at any time.
Yes, agreed.
I suspect that the on_idle_new_doc() function is being called while the program is exiting and thats causing both the warnings you are seeing and the segfault I'm seeing (I also see warnings like you're seeing).
Ok, this is really quite nasty. Here a backtrace capture with --g-fatal-warnings on. The line numbers may be just a little off because I added some debug printfs.

First thing to note is that this is definitely happening when the geany is being closed (ie clicking on the top right close window button).
The trace above is all about this function
GeanyDocument *document_new_file_if_non_open(void) { if (gtk_notebook_get_n_pages(GTK_NOTEBOOK(main_widgets.notebook)) == 0) return document_new_file(NULL, NULL, NULL);
return NULL; }
I added some debug printfs here and found that main_widgets.notebook is not NULL, but is still not a valid GtkNoteBook, probably because it has already received a destroy message.
I'm not sure of the best way to fix this.
