[rabbitmq-discuss] RabbitMQ .NET Client Bug - ModelBase.BasicCancel Always Throws An Exception

[joefitzgerald]

Folks,

I have run across an issue with ModelBase.BasicCancel which appears to be a 
defect. The following statement always throws a NullReferenceException 
here: 
http://hg.rabbitmq.com/rabbitmq-dotnet-client/file/0037c3b3fa8d/projects/client/RabbitMQ.Client/src/client/impl/ModelBase.cs#l1135.

The 'k' object is instantiated here: 
http://hg.rabbitmq.com/rabbitmq-dotnet-client/file/0037c3b3fa8d/projects/client/RabbitMQ.Client/src/client/impl/ModelBase.cs#l1117, and 
it appears that k.m_consumer is never initialized (nor can it be), leading 
to the null reference exception.

I've created a fix for the issue and validated that this lets 
ModelBase.BasicCancel work as expected. Can someone please look at this 
pull request and provide comments or merge to 
master? https://github.com/rabbitmq/rabbitmq-dotnet-client/pull/11

Cheers,
Joe
