Bug in RaygunClientBase in C#

The class Mindscape.Raygun4Net.RaygunClientBase has a bug in its implementation of FlagAsSent which has the following (decompiled) code:

internal void FlagAsSent(Exception exception)
{
  if (exception == null)
    return;
  exception.Data[(object) "AlreadySentByRaygun"] = (object) true;
}

The problem:

Exception.Data is a virtual property that can be overridden and return a generic dictionary where the key is not a string. For example, in RabbitMQ, the class BrokerUnreachableException overrides Data like so:

public override IDictionary Data
{
  get
  {
    return (IDictionary) new Dictionary<AmqpTcpEndpoint, Exception>(this.m_connectionErrors);
  }
}

This causes an exception in the raygun code because it's trying to insert a value in the dictionary with a string key.

Workarounds:

I surround all invocations to raygun with a try/catch. This is not ideal and also misses the point since Raygun doesn't receive the original error.

Suggested Solution:

Either use a try/catch in FlagAsSent or check the type of the dictionary to ensure it is not a generic dictionary that prohibits string keys.

We are having this problem too ..

How can we follow - when this is fixed so we can get the latest package?

Thanks
