Export to Excel results in Error: Can't set headers after they are sent #81

Thank you otetard for the ethercalc integration into Nextcloud!

It works great here, except when I want to Save/Export a sheet to Excel. The ethercalc stops with this stacktrace (see below).

Exporting a sheet directly out of the ethercalc app without using Nextcloud works, on the other hand.

Any help in resolving this issue is much appreciated!

Hint, maybe? http://www.nodejsrecipes.com/recipes/7042340/error-cant-set-headers-after-they-are-sent-to-the-client
