Smuxi

Are you using smuxi-server? If so, which side have you upgraded to 2.10.1?

For the record: smuxi-server on mono 2.6.7 and smuxi-frontend-gnome on mono 2.10.1 works for me

server is: Mono JIT compiler version 2.10.1 (tarball Mon Apr 11 15:46:24 UTC 2011)

mono --version

gui runs on windows (not mono). It worked before I updated the server to 2.10

Installed from a binary package, I think the "Other "package.

So Mono 2.10.1 is no longer ABI (Remoting) compatible with .NET 3.5, that is very sad. I hope this will be fixed in Mono. Can you give Mono 2.10.2 a try?

There is no known workaround yet. Mono 2.10.x broke ABI compatibility with MS .NET when it comes to the System.Collections.Generic.Dictionary<K, V> type which Smuxi makes use of. We will need a fix in Mono for this issue.

Has this bug been reported upstream? If so, do you have a link to the case? I'm having the same issue in my code and would like to look into fixing it.

I never experienced this issue with Mono 2.10.8 so I think I can assume the issue is no longer present

https://bugzilla.xamarin.com/show_bug.cgi?id=3050

This issue only becomes visible when the smuxi-server runs on Mono 2.10 and the frontend on Microsoft .NET

The only known workaround is to use Mono on Windows

Most people start to only see this issue when they add a Twitter account for some reason. Here is such sample:

Exception Type:
System.InvalidCastException

Exception Message:

The real fix of this issue will come with switching to a new RPC system like REST. HTTP/JSON/REST does not rely on binary serialization like .NET remoting currently does.

Smuxi is now detecting this issue and shows a dialog with a link to resolve the issue instead of crashing.
