bug#65629: 29.1; Dictionary-search on Windows : wrong-type-argument stringp nil in dictionary-read-reply-and-split()

[Paul van Gelder]

You're right that port 2628 must be blocked by my company's firewall: the 
MacBook was on the company guest network, the Windows laptop on the corporate 
network.

I just brought my Windows laptop home to check on my personal network, and it's 
working fine (with init file and with -Q).

My apologies for wasting your time - I'll include a connectivity check in my 
checklist for troubleshooting issues before reporting a bug report next time.

Thanks for your quick response.
