How to quit gtk_main with freeing memory?

[ralf deres-mueller de]

Hello,

using valgrind gives me hundreds of errors because I use 

gtk_exit(0); or gtk_main_quit();

e.g.:

==2290== 36 bytes in 1 blocks are definitely lost in loss record 48 of 160
==2290==    at 0x40026422: malloc (vg_replace_malloc.c:153)
==2290==    by 0x40FC52FE: (within /lib/libc-2.3.2.so)
==2290==    by 0x40FC4BE4: __nss_database_lookup (in /lib/libc-2.3.2.so)
==2290==    by 0x4358F10C: ???

==2290== 
==2290== 36 bytes in 3 blocks are still reachable in loss record 49 of 160
==2290==    at 0x40026422: malloc (vg_replace_malloc.c:153)
==2290==    by 0x4103B470: FcExprCreateDouble (in /usr/lib/libfontconfig.so.1.0.4)
==2290==    by 0x4103CB74: (within /usr/lib/libfontconfig.so.1.0.4)
==2290==    by 0x4103CBC2: (within /usr/lib/libfontconfig.so.1.0.4)
==2290== 

How can I cleanup memory before exiting the program?
