[Bug 1267116] Re: ubiquity crashed with SIGSEGV in GtkNode::MatchStringProperty()

[Martin Pitt]

For the record, the only occurances of std::string in
GtkNode::MatchStringProperty are now the method arguments; they are
const references though, and shouldn't be handled at all at method exit.
The stack trace doesn't make too much sense to me, though (i. e., why
does the std::string destructor call GtkNode::MatchStringProperty()?)

** Package changed: ubiquity (Ubuntu) => autopilot-gtk (Ubuntu)
