crash when searching

[bukzor]

Reproduction steps:

1. python -m pudb.run foo.py
2. /
3. foo
4. <enter>
5. The below traceback is displayed.

If you can tell me how to induce this error automatically, I can write a unit test for it, at minimum, and likely produce a patch for the bug as well.

What version of urwid are you using?

[inducer]

I should add that I currently can't reproduce this issue.

[asmeurer]

Perhaps the contents of foo.py are relevant.

[bukzor]

my pudb is the latest pypi. I'll try the github version shortly.

$ python -V
Python 2.6.7

$ pip freeze | egrep 'urwid|pudb'
pudb==2012.3
urwid==1.1.1

foo.py is entirely trivial:

def foo():
    print 'ok'

foo()

[asmeurer]

I can reproduce this. It seems to be an issue with the newer urwid (pip still installs version 1.0.2 for me for some reason).

[inducer]

Should be fixed in git. urwid changed the interface for what I'm trying to do there (delete the search box), and the backwards compatibility shim isn't exactly backwards compatible. I did what I had to do to fix this: Use the new interface, require urwid 1.1.1.

[inducer]

Uh, nope. Didn't fix it.

[inducer]

Never mind. Urwid 1.0.1 had crept back into my virtualenv. Should be fine.
