Comment 4 for bug 793627

We are getting the same error on 2.2.1.

It is caused by missing hours of operation but not how you would expect. On my live and test system I can checkout odd numbers of items and the receipt will print. If I checkout an even number of items the system hangs trying to print the receipt.

I added the following to the template to debug:

[% USE Dumper(Indent=0, Pad="<br>") %]
[% Dumper.dump(target) %]

When I checkout an odd number of items I get the the full list of hours:

bless([
'20:00:00',
'09:00:00',
'20:00:00',
'09:00:00',
etc.

When I checkout an even number of items I get the following for the hours:

'20:00:00'

Just a single time is returned and no bless([ ]) wrapping it.
