Description of problem:
After opening the attached word document, quiting abiword causes glibc to detect
an invalid pointer on free.

Version-Release number of selected component (if applicable):
abiword-2.4.4-2.fc5
fontconfig-2.3.94-1
libXft-2.1.8.2-3.2

How reproducible:
always


Steps to Reproduce:
1. open attached file in abiword
2. quit abiword

  
Actual results:
(AbiWord-2.4:27802): GModule-CRITICAL **: g_module_close: assertion `module !=
NULL' failed

(AbiWord-2.4:27802): libgsf:msole-CRITICAL **: ole_get_block: assertion `block <
ole->info->max_block' failed
*** glibc detected *** abiword: munmap_chunk(): invalid pointer:
0x000000000102e800 ***
