When GStreamer is loading plugins, it traps SEGV. After it's done, it resets
the handler to the default one, and not the previous one.

This leads to unhandled segfaults in Mono applications that use GStreamer, as
the Mono runtime traps SEGV to translate the dereferencing of null pointers
into NullReferenceExceptions. This means applications that have code to handle
NullReferenceException can never recover as expected. Instead the application
simply crashes.
