Theme download using ftp:// fails when http_proxy is set

[pmhahn@…]

When I try to download the Arclight theme in the ThemeDownload?, I just see something popup for just some micro seconds and then I'm back to the list of themes. Only running "mythfrontend --loglevel debug -v file,network" shows the following failure:

That "No suitable proxy found" comes from Qt <​http://qt.gitorious.net/qt/qtbase/blobs/43b6320a5a1e740e7b3dbc8fe623bd83903ad172/src/network/access/qnetworkreplyhttpimpl.cpp#line605>, but all downloads using ​ftp:// seem to fail. I have http_proxy=​http://localhost:80 configured to use my local apache as proxy, which has only proxy_http but not proxy_ftp enabled. Unsetting http_proxy makes it work (even thou I have to select a theme twice to get it activated; it seems to be downloaded twice?)

MythTV should at least provide a more prominent hint on what went wrong.

I had the same problem on Windows with 0.25-fixes when an HTTP proxy is set.

The easiest solution to this is to just use ​http://ftp.osuosl.org to download themes rather than ​ftp://ftp.osuosl.org. I have modified the theme packaging script and regenerated the themeinfo.xml files and themes.zip index files on the server. The FTP proxy issue should not be a problem anymore. The Theme Chooser (via MythDownloadManager?) should now use your HTTP proxy to get to the themes packages.
