After you enable Wikipedia or/and Wikidictionary as GoldenDict dictionaryies via GoldenDIct menu, you still can not use them, because it fails to obtain query from wikipedia. It shows only warning:
Query error: XML parse error: unexpected end of file at 1,1
I use latest GoldenDict GIT version 20151231T154233-617.1 from https://software.opensuse.org/download.html?package=goldendict&project=office:goldendict in openSUSE.
P.S. This is different Wikipedia in GoldenDict bug from https://github.com/goldendict/goldendict/issues/642 as it is not about "SSL handshake failed".
I have the same bug in Ubuntu 15.10. The version is called 1.5.0~git20131003-1build4.
Change "http" to "https" in wikipedia urls .
Yeah, that works. If the URLs have been updated on GitHub then it seems this should be closed as fixed.
