Actually it looks like it's gnome-disk-utility that does the unmount and throws the error. I can't for the life of me figure out this rat nest of code though. In gduresizedialog.c, resize() calls gdu_utils_ensure_unused() and passes it unmount_cb(), which appears to be what is throwing that error message after the unmount fails. What I can't see is where the actual unmount is done. gdu_utils_ensure_unused() appears to call g_task_new to set up a task to invoke that callback after the task itself as run, but I see no call to g_task_run_in_thread() which would actually specify the task function to run, and make it run.
