I can confirm that I am experiencing the same bug with KeePass v2.28 under Mono v3.2.8 on Lubuntu v14.04. I am using two local dbs and one of them has a custom colour. I tested it with two dbs without the custom colour, and it worked fine on changing tabs without crashing. Then I added the third db which has a custom colour and it crashed on changing tabs with the following error message:
System.ArgumentException: Cannot add Control to TabControl.
