Bug#28012 Patch : IM crashes instead of reporting an error when mysqldpath is bad

Browse Source 
On the windows platform, if an instance object failed to initialize during
program start, the instance manager would crash.
This could happen if an incorrect mysqld path was supplied in the 
defaults configuration file.
The patch prevents the program from crashing and makes it show an
error message instead.
