When I look in the Ubuntu Software Centre, I see a few choices:
Umbrello: KDE so thats out as I use XFCE. Reviewed as horrendously buggy.
Gaphor: Reviewed as very basic and horrendously buggy.
BOUML: Reviewed as horrendously buggy along with an almost unusable GUI.
Dia looks like a candidate but it doesn't appear to have full UML modeling.
Is there a good UML modeler available for Linux or are Gaphor and BOUML better than reviewed?
