ukuu window disapears after removing kernel

[kseyhan]

On Ubuntu 17.10 the Ukuu Window disapears after i remove a installed kernel but the process is still alive.

In the syslog i found this message after (but i'm not sure if its realy related or another bug):

Jan 17 21:14:46 xxx ukuu-gtk[18500]: Drawing a gadget with negative dimensions. Did you forget to allocate a size? (node progress owner GtkProgressBar) Jan 17 21:14:46 xxx ukuu-gtk[18500]: Allocating size to MainWindow 0x55b074d92420 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate?
