[Click] About element_error_hook

[Roberto Riggio]

Hi,

a question for the core developer. I'm trying to track down a bug in my code and
at some point I get a segmentation fault with the following details:

[Switching to Thread 0xb7c776c0 (LWP 26846)]
0x0819a483 in element_error_hook (val=0xbfe6c898) at ../lib/error.cc:743
743	    return e->declaration();

In which situation is element_error_hook called and by who (The method declaration is not
overridden by my element).

R.
