Openoffice freezes when trying to add special character

Binary package hint: openoffice.org2

Openoffice.org freezes when I try to add a manual break, section, hyperlink, special character, header, index element, change the language settings and similar.

It completely locks up, and I have to click the "close" button several times for the "Terminate program" dialogue to appear, so I can close the program.

My console outputs this (when I try to add a header):

*** glibc detected *** /usr/lib/openoffice/program/soffice.bin: free(): invalid pointer: 0x09007ea0 ***

Is there any way to fix this?
