Bug Description

Binary package hint: python-launchpad-bugs

I used bughelper to find some bugs:

$ bughelper --cookie=$HOME/.mozilla/firefox/*/cookies.txt -T compiz "workaroundsRemoveFromFullscreenList" "WA problem" -p compiz
'Checked at [] - no clues found. Check README on how to create one using the bugxml(1) command.'
Traceback (most recent call last):
  File "/usr/bin/bughelper", line 228, in <module>
    main()
  File "/usr/bin/bughelper", line 172, in main
    info_file = files.get_info_file(b.sourcepackage, cl.options.verbose)
  File "/usr/lib/python2.5/site-packages/launchpadbugs/bugbase.py", line 17, in <lambda>
    if fget : fget = lambda s, n=fget.__name__ : getattr(s, n)()
  File "/usr/lib/python2.5/site-packages/launchpadbugs/html_bug.py", line 128, in f
    x = a.infotable.current
  File "/usr/lib/python2.5/site-packages/launchpadbugs/bugbase.py", line 17, in <lambda>
    if fget : fget = lambda s, n=fget.__name__ : getattr(s, n)()

    x.parse()
  File "/usr/lib/python2.5/site-packages/launchpadbugs/html_bug.py", line 503, in parse
    assert type, "Wrong XPath-Expr in InfoTable.parse() 'type' (%s)" %(DEBUG_URL or "unknown")
AssertionError: Wrong XPath-Expr in InfoTable.parse() 'type' (https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/141472)

I'm not sure whether I did something wrong since I've never really used bughelper before, but this looks like a bug.

Hi Kjell,
thanks for reporting this, this is really a bug in python-launchpad-bugs.

The reason for this bug is that the way of handling remote bugreports in "https://bugs.edge.launchpad.net" changed.
You can workaround this issue by not defineing '--cookie'.

Working on a fix.

This patch against py-lp-bugs .main rev57 fixes this issue,
needs some testing before committing to .main.

Test case:
In [1]: import launchpadbugs.connector as Connector

In [2]: Bug = Connector.ConnectBug()

In [3]: Bug.authentication = {"password": "******", "email":"<email address hidden>"}

In [4]: b = Bug(url="https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/141472")

In [5]: print b.infotable
[[Compiz (remote): Confirmed/Unknown],[compiz (Ubuntu): New/Undecided]]

If you are member of 'launchpad-beta-testers' and did not apply the patch, the last statement would raise the Error in the description of this bugreport.
