Crash on LHC upload

Description

Many people have been reporting crashes when the core client attempts an upload or scheduler request to LHC@Home project. LHC is currently down for maintenance. All pages under the domain name lhcathome.cern.ch return an HTTP redirect to http://lhcathome.cern.ch/. This is probably part of the crash cause.

Based on symbol-less stack dumps posted by users, I tracked it down to a curl_multi_remove_handle call. I believe it's being passed an invalid handle, but I'm not sure yet.

Full stackdump:
