strange listener behavior after a 'in escape sequence' error in guile-1.8

[David Séverin]

Hello,

        debian
        2.6.26-1-vserver-686
        guile 1.8.5+1-4.1

Through a mistake of mine, I raised something 'strange' in guile-1.8
that did not occur in guile-1.6 [see here below], and was wondering if
it is the expected behavior?

Cheers,
David

In some of my code, I wrongly escaped a character which did not need
to be, as is:

        "On\/Before"

In guile-1.6, it just returns the string "On/Before"

In guile-1.8, I get an error, which is fine, but then and there after
the listener gets crasy what ever you are trying to evaluate, until I
provoque a 'User interrupt':
