tested latest Windows wallet 1.5.2, seems to solve masternode.conf crash issue

Rebuild linux wallet and downloaded 1.5.2 for win. Win wallet still crashed with masternode.conf file.
Same issue here. Have done the same steps and when there's a line in the masternode.conf file, the wallet crashes. Now started my MN via the interzone.conf file, by setting the masternode* properties.
Hope the masternode.conf method gets fixed;
Windows wallet 1.5.2 solved this problem for me. Could you share your steps before starting a MN? We may figure it out.
