Subdownloader does not load the full list of subtitles/movies

[Andrey Skvortsov]

System information:
Subdownloader 2.0.10 / Linux

Problem:
When I search by Movie Name in Subdownloader, it loads not all results from server. It shows only the first 40 movies.
This problem appears also, when I expand in GUI tree with selected film, that has more than 200 subtitles. I can see only first 40 subtitles.

Site http://opensubtitles.org returns only 40 records on one request. Subdowloader requests only one page, for example, like this:
http://www.opensubtitles.com/en/search/sublanguageid-all/xml/idmovie-174

And subsequent data (movies or subtitles) must be loaded from this pages:
http://www.opensubtitles.com/en/search/sublanguageid-all/xml/idmovie-174/offset-40,
http://www.opensubtitles.com/en/search/sublanguageid-all/xml/idmovie-174/offset-80,
http://www.opensubtitles.com/en/search/sublanguageid-all/xml/idmovie-174/offset-120,...

Subdownloader with this patch requests pages until it get page with no data.

I got also sometimes KeyError exceptions on movies, whose description has no field 'MovieName',
There are sometimes Attribute exception on some subtitles, the patch correct this also.

Could you provide a diff -ruNb or a bzr diff ? I'll really appreciate it.

Thanks
