[PATCH] Correct internationalization of exception handler text

[Matt Wilson <msw rpath com>]

Currently constants.exceptionText won't translate properly because
string interpolation is performed inside _().  This patch splits the
string up so you get generic text if no bugUrl is set in the product
definition, and also corrects this problem.
