Products with a number [0-9] as first character

-- HikaShop version -- : 1405141023
-- Joomla version -- : 3.2.4
-- PHP version -- : 5.3.3
-- Browser(s) name and version -- : Firefox / chrome / IE
-- Error-message(debug-mod must be tuned on) -- : Cannot display product

I was recently having a problem with new products not displaying in the catalog that upon further testing found out that if the product name started with a number, then the auto-created alias would have have the number first which caused some internal problem as when I tried to view the product in the catalog hikashop would say that the product could not be found.

For example, the product name set set was: 6 Mahogany English Chippendale Chairs
which created the alias: 6-mahogany-english-chippendale-chairs

And when browsing the store as a user, when I clicked on the alias /6-mahogany-english-chippendale-chairs, it would go to the product page and then say "Product not found".

If I updated the alias to not have the number in the beginning the error went away.

Thank you

I am rebuilding a site and imported data from Virtuemart. All went well but some products with names starting with a number were not displayed. Perhaps the checking is not done when importing? There weren't too many so I edited them in the database by add a 'p' in front of the alias.
There were also some categories that were not working and on inspection the alias was missing. I couldn't see the reason for this.

Best regards
