Fix to access old TDE wallet with special characters (R14.0.x series) #16

Same as #15 but for R14.0.x series

Problem with previous patch version identified and resolved. This was a similar problem as we recently dealt with in KPasswordEdit::password().

Calling TQString::fromLocal8Bit( "..." ) creates a temporary TQString object, but the subsequent use of const char * obtained by the ascii() method then refers to a portion of memory that has already been released and used for another purpose.

With a modified version of the patch, opening a wallet with a password with special characters works also in R14.0.6.

Great! I think we are ready to merge then
