Running a program that uses urwid under python 3.14 it crashes with

    RuntimeError: There is no current event loop in thread 'MainThread'.

I believe this is the following upstream bug

https://github.com/urwid/urwid/issues/951

which should be fixed in one of the latest upstream releases, could you
please update the package?

I've marked the bug as important, I'm not sure whether there are other
ways to use urwid that still work, but if there aren't maybe the
severity is even higher?

Thanks in advance.

The new urwid has been packaged in Debian Testing/Unstable.
