A patch for this bug has been committed. After review, it may
be pushed to the relevant source trees for release in the next
version. You can access the patch from:

When parser parses function convert_tz it loads available timezone tables in
  thd->lex->time_zone_tables_used. But view have another lex that main query.
  Thus time_zone_tables_used of main query left uninitialized.
  When Item_func_conver_tz is fixed it takes timezone tables from main query
  and later when it executed it assumes that timezone tables are loaded and
  failed that assertion.

Fixed in 5.0.14, cset 1.1958.3.1

Noted in 5.0.14 changelog.
