Comment 16 for bug 888504

I suspect getcontenttype does not contain the expected "text/calendar" and this is why it's not working, could someone add the trace of a session?

1) Install Console2 addon: https://addons.mozilla.org/en-US/firefox/addon/console%C2%B2/
2) Set both preferences calendar.debug.log and calendar.debug.log.verbose to true
3) Restart thunderbird
4) After the error, go to Tools->Error Console, Ctrl-A to select all lines and copy that to a text file that you attach to this bug.

Thanks
