glibc utility function errors

[Matt Bragano <maestro485 comcast net>]

Every time I use the glibc utility functions (Glib::get_home_directory() 
specifically), I receive this runtime error:

*** glibc detected *** double free or corruption (out): 0x080827f8 ***

However, if I replace Glib::get_home_directory() with a hard coded path 
(i.e. /home/matt/) everything seems to work fine.

I'm fairly new to both c++ and gtkmm, so please excuse me if this is an 
obvious thing or the wrong list.

Thanks,
Matt
