Comment 3 for bug 1322325

I've fixed the original issue documented in this bug, Invalid control character, in r574 of errors by using encodeURIComponent to pass the signature to the create-bug API and then unquoting the signature in that API call.

As an interim solution to the long bug title I've committed r721 of daisy which uses the source package name and the last line of the Traceback for the bug title. Certainly, using standard_title from apport would be better but this'll help in the interim.
