I located the bugs in loader_controller.rb
Seems as version.effective_date, issue.start_date and issue.due_date get tot checkd if they are set before time conversion.
I added an "if issue.start_date" or if "issue.due_date" or "if version.effective_date" behind these lines. to check before.
No i can export an xml.
But am not sure if Ms Project will allow xml files without that xml elements.
So far these attributes are not mandatory in redmine, so an exporter can expect them to be set. It must be checked and maybe setting to "0" will be better for Ms project import compatability than not set them in the xml.
Maybe ist not possible at all to import task or versions wthout dates, so this items muts be skipped completly, but that would be bad to sync status of both tools.

You can try my fork.

Unfortunately, there still many issues with MS Project itself, we can't make it to import XML properly.

The bugs i reported are on ur fork. Would be great if you enable githubs issue module so i can report and push there.

Which bugs are open. Please write a list, so we know what shall be fixed
