Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
=================================================================

Aborted (core dumped)

Expected Results:
The function on the server should return the string

How often does this happen? 
Everytime

The bug is about using explicit interface implementation.
Already fixed in SVN, dupe of bug #324232.
