Bug Description

Binary package hint: python2.6

This python segfault happens reproducible when running lp:zeitgeist-filesystem
I'm not sure what exactly goes wrong, will try to debug it over the weekend.

Note: this filesystem is NOT using python-fuse binding for FUSE, but fusepy from http://code.google.com/p/fusepy/

Thank you for helping making Ubuntu and Zeitgeist better by reporting this bug. However, before we can pass this on to the developers we need some more information.

You said you can reproduce this bug when using lp:zeitgeist-filesystem. If this is a bug in the development branch rather than the version available from the repositories, you should report this bug against the project Zeitgeist, <https://launchpad.net/zeitgeist>, because this bug is Invalid for Ubuntu.

Zeitgeist is still under heavy development and subject to rapid changes. Maybe this bug has already been fixed. Can you still reproduce it with the latest version of Zeitgeist available from the repositories?

I'm marking this bug as Invalid because there was no response for one month after I asked and the bug was reported more than five months ago. I'm assuming this is already fixed by now.
However, if you do stumble on this bug again and are willing to provide more information, please don't hesitate to reopen the bug.
Thanks!
