Empty user_dateformat field causes post dates to not be displayed (fix completed in vcs)
PHPBB treats empty user_dateformat fields as a custom date/time format, which causes the date displayed on forum indexes to not show.
This is particularly the case when converting to PHPBB3, the user_dateformat column can sometimes be left blank for users (eg: SMF->PHPBB).
EXPECTED BEHAVIOUR:
That in the absence of a date format value in a user's user_dateformat property, a sane default to be used (the global forum date format, perhaps?).
MORE INFORMATION:
This bug was discovered when converting from SMF->PHPBB2->PHPBB3, discussion and analysis can be found here:

I'll add a workaround to the converter, but I don't think this warrants changes in the core code.
