Hi Lex,
Many thanks for your reply. I will try and see if I can make minimal reproduction code that I can use for testing on mono-2.6, 2.10 and 3.0
I will keep you posted on what happens :-)
The reason that I an actually using 3.0 is this "quote" from the release notes:
<quote http://www.mono-project.com/Release_Notes_Mono_3.0.3>
Mono 3.0 is an update to
Mono 2.10 based on the master branch of github, it is not a minor upgrade to 2.10. Mono 3.0 was released on October 18th 2012.
We will continue to bug fix and update Mono 2.10 for another six months for users that can not upgrade to Mono 3.0.
