btw.. im using kde-3.4 and ksayit-0.83 from kdeaccessibility-3.4 

Maybe you mixed things compiled with gcc-3.3 and gcc3.4? 
Try doing 'revdep-rebuild -X --soname libstdc++.so.5' 

I've seen this problem on a machine that had a borked gcc/glibc upgrade.  You 
need to make sure all of the libraries are build against the newest glibc. 

Created an attachment (id=73694) [edit]
ksayit-3.4.3-invalid_free.patch

Proposed patch to work around glibc invalid pointer errors.  Works without
MALLOC_CHECK_ workarounds.

I have tested the patch and it also works well here, where before I had to use 
the glibc workaround. I have committed ksayit-3.4.3-r1 and 
kdeaccessibility-3.4.3-r1 to the tree. I would like to get these stabilised 
ASAP as the fix is quite simple and works here. Thanks to Chris for providing 
the patch. 

Closing.
