Comment 1 for bug 1745521

Not reproduced on Windows 7 with Inkscape 0.92.2 (5c3e80d, 2017-08-06).
The search is executed properly and available clip arts are listed.

I assume the search request to openclipart.org times out for some reason - can you figure out why this request can not complete on your machine (e.g. proxy settings / security software / whatever)?

Note that if the server is unreachable (i.e. no internet connection) Inkscape does not attempt a search and informs the user accordingly, so it has to be something less obvious.
