Flight Crew: Premature end of document

[icallaci]

Sigil 0.9.1 is working great, except for one minor problem, which I'm sure is my fault. When I use Calibre's "Open With" plugin to open an epub with Sigil, and then run Flight Crew, I get the following error: Error Parsing Result XML: Premature end of document. (I don't receive this error if I open Sigil from the desktop.) Looks like a problem with the path, but I'm not sure how to fix it. Thanks for any help. Traceback below:

A few things ...

- Running Sigil, just to run flightcrew does not make a lot of sense. It would be much easier for someone to create a flightcrew plugin for calibre directly as flightcrew is now a simple command line tool and calibre has great plugin developers and support who could easily create a flightcrew plugin for calibre.

- the Calibre "Open With" sequence seems to be unsetting the PATH environment variable which causes the ctypes find_library module used in the plugin launcher to fail deep inside of the official python 2.7 os module. The os module seems to need/want PATH to at least exist.

Thanks, I use Sigil for more than simply running Flight Crew, but it's usually one of the last steps in my workflow, so I guess I'll have to be satisfied with Calibre's Edit Book/Check Book for now. (I usually run both as they seem to catch different things.) Anyway, thanks.

Use calibre's builtin Open With feature, not the the Open With plugin.

The plugin special-cases Sigil in order to work around bugs that no longer seem to exist. The problem is that unsetting the PATH also messes things up...

The problem is the way the Open With plugin launches Sigil. The fix is to modify the calibre OpenWith plugin or to use calibre's built-in Open With feature that doesn't suffer from the same issue.

Aha, I didn't know about Calibre's built-in Open With feature. I'll try that. Thanks.

Edit: It works! Thanks so much. I'm back in business.
