Weird Extractor plugin error (Solved)

[pho]

I just installed Backtrack r5 and deluge 1.3.2 and for some reason the Extractor plugin has an error (below). All other plugins including 3rd party Toggle and Graphs work fine. I have no such problem on another machine with a similar setup and the extractor works fine there. Ive installed all the dependencies for Ubuntu/Debian so this has me stumped, any help would be appreciated.

I cannot reproduce your issue, have you verified the md5sum of the deluge archive then tried re-installation?

Could you list the contents of this directory:

I will try re-installing later today when i get home from work. It could be I screwed up the with the --install-layout=deb switch when I installed, I cant remember. I did it in quite a hurry as I was trying to get through setting up a fresh OS as quickly as possible. Ill post back my results after a reinstall.

Well I noticed you updated the Deluge PPA so I added it to my repository and reinstalled 1.3.2-1~lucid~ppa3. Also updated libtorrent to 0.15.6-2~lucid~ppa1.

The Extractor plugin still wont enable. All other plugins still work fine.

At this point I'm guessing there is something wrong with my Python but I cant figure it out yet. If anyone has any ideas about what might be going wrong, I'd appreciate the input.

Can you see if that file /usr/lib/pymodules/python2.6/extractor.pyc exists and if so create backup then delete it.

Maybe you have a python module call extractor that is causing problems? Does python -c 'import extractor' give you an error?

[pho]

Can you see if that file /usr/lib/pymodules/python2.6/extractor.pyc exists and if so create backup then delete it.

OK tried that, restarted deluged and deluge-gtk, checked to enable extractor, it recompiled extractor.py into extractor.pyc and I still get the exact same error.

Is there something I can do to increase the the error logging into something that actually has a meaning to me (or you)? Ive read the code around the error points in the relevant files and searched through a buncha files for anything that has "CorePlugin" in it and came up with no search results. Im a fair programmer, but Im not very familiar with python or the deluge code but it seems to me there should be something else I can do to to track down this error.

Maybe you have a python module call extractor that is causing problems? Does python -c 'import extractor' give you an error?

No error there, no output at all. Which I think should be good.

No, thats bad. It means that there is an extractor python module that Deluge tries to import instead of the extractor plugin. Probably a bug in Deluge why it does this, but thats likely the problem you're encountering.

hmm I think you may be onto something here. I looked at the file deluge is trying to run as the extractor plugin /usr/lib/pymodules/python2.6/extractor.py in a text editor and I dont think its related to deluge ... heres the first bit of the file ...

This does not look right So, what can I do about it? Any Suggestions?

[pho]

Yep that was the problem, I found some packages that had been installed by default in the distro, namely "metagoofil", which required a package called "extract", which required "libextractor" and "libextractor-plugins".

I uninstalled these packages, restart deluge and the extractor plugin now works.

Not sure what can be done on the development of deluge to try and prevent this error for others other than renaming extractor.py to something nobody else would use.

Thanks andar and cas for helping me, nice catch.
