I have imported an image. I add a new text zone box over it, write some text, highlight that text and select Format/Align/Center. Writer crash.
Thanks for reporting the bug. It seems what you've encountered is the same as bug 130482, and it has been fixed in the source code repository. A fixed version will be released for 6.4.2. I'm going to mark this bug as a DUPLICATE. If you think it's a different bug, just change the status back to UNCONFIRMED. *** This bug has been marked as a duplicate of bug 130482 ***
Sorry, bug 130286 is probably closer to what happened here. *** This bug has been marked as a duplicate of bug 130286 ***
