Bug#481911: elisa: incompatible with twisted 8

[Zack Weinberg]

Package: elisa
Version: 0.3.5-3
Severity: grave
Justification: renders package unusable

When I start up Elisa, I get a mangled display and a bunch of Python
stacktraces (quoted below).  I reported these to the upstream support
forums at http://elisa.fluendo.com/forums/viewtopic.php?pid=1831 and
was told, in so many words, that Elisa does not yet support Twisted 8
and they would be grateful for patches.

As the only version of Twisted available in testing or unstable is
8.0.1, this effectively renders the package unusable.  I may try to
come up with patches but I don't know anything about Twisted or
elisa's internals.

A problem occurred in a Python script.  Here is the sequence of
function calls leading up to the error, in the order they occurred.

The above is a description of an error in a Python program.  Here is
the original traceback:
