r19986 - gnucash/trunk/src/gnome-utils - Fix more memory leaks. scm_to_locale_string() returns a string which must be freed.

[Christian Stimming]

Dear Phil,

unfortunately this (r19985..r19988) break the start-up of gnucash here. I've 
got guile-1.6.8, so I suspect you have guile-1.8 and it's a guile think here. 

At r19985 I don't have a crash at start-up but instead at shutdown; since 
r19986 I've got the crash at start-up as shown below.

Regards,

Christian
