According to the statistics of the gnome buzilla concerning the dia

Also, dia ranks #8 among all apps on the gnome CVS concerning statics of
patches not reviewed.
-> dia 59% (19/32) 19 bugs reviewed among 32.
I just hope you can manage to close/reopen/comment those bugs to get
this application better.
