Ive got the same exact problem. Tried what danimalanimal i suggesting and then it works until i delete the category, then the page stops working.
Im running apache 2.0.52 on CentOS and PHP 4.3.9 with Zend Optimizer v3.0.1 and WP 2.1
At least its not a showstopper anymore, and it can be worked around.
I have the exact same problem. Everything works in WP admin except manage categories.
I get the following error in my log file:
*** glibc detected *** corrupted double-linked list: 0x0a30aae8 ***
Ive searched a bit on google, and some people pointed it towards zend optimizer, which i disable, but the problem still persists.
Im running apache 2.0.52 on CentOS and PHP 4.3.9 with Zend Optimizer v3.0.1 and WP 2.1
Upgrading to PHP 5 is not an option.
Would very much like to hear input on this. Thanks in advance.
