Python segfaults when running Plucker

[James Valentine]

Binary package hint: plucker

When running plucker, Python segfaults and dumps core partway through the spidering procedure. The same home.html worked perfectly before Python 2.3, as far as I can remember.

Edgy's bug report will be attached immediately.

[Rich Johnson (nixternal)]

Attached debdiff. changes debian/plucker.install to link to /usr/lib/python2.4 instead of /usr/lib/python* which would grab the /usr/lib/python2.3 link first. This fixes this issue.

[Rich Johnson (nixternal)]

see attached debdiff above

This will be fixed with a new release I am currently working on (v1.9). It will make it to stable releases as a backport in due time.

[Rich Johnson (nixternal)]

We are awaiting a new upstream library to be release and then this will be released as well. I apologize for the delay.

This bug should be closed now that plucker uses python-central to manage the python modules.
