Answer

This probably means the smuxi-server is running on Mono 2.10 which uses the .NET 4.0 runtime profile while the Windows frontend uses the .NET 2.0/3.5 runtime profile.

To verify if the smuxi-server uses .NET 4.0, run this command:
monodis --assemblyref /usr/lib/smuxi/smuxi-server.exe
If that shows output like this:
AssemblyRef Table
1: Version=4.0.0.0
        Name=mscorlib
        Flags=0x00000000
        Public Key:
0x00000000: B7 7A 5C 56 19 34 E0 89

See the Version=4.0.0.0? That means smuxi-server runs on .NET 4.0

Now you need to force the smuxi-server to use the .NET 2.0/3.5 profile again by starting it like this:
mono --runtime=v2.0.0.0 /usr/lib/smuxi/smuxi-server.exe
Or you need to force the Windows frontend to use the .NET 4.0 profile by adding a smuxi-frontend-gnome.exe.config file to the application directory with this as content:
<?xml version="1.0"?>
<configuration>
    <startup useLegacyV2RuntimeActivationPolicy="true">
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>

        <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
    </configSections>
    <log4net>

            </layout>

</configuration>
