Bad talloc magic value - unknown value when not connected to the internet

[haemi]

When I'm not connected to the internet and try to send a file via

       [provider fetchAtPath:completePath block:^(id result) {
                 ...
       }];

I get Bad talloc magic value - unknown value.

I have the same problem and I noticed that this happens when I try to access a symbolic link (e.g. www.github.com/file.zip) when not connected to the internet or in mobile data mode.
A workaround is to convert the symbolic name into an ip address on your own and then call kxsmb with the ip.
