I had the same problem and didnt find how to fix it, so i decided to update to BASE :

its build on ACID, works fine, you can keep your mysql database, just have to config a file and its ok.

I an update/upgrade this morning and after updating acidlab several
functions are not working.
Example - select check boxes not working
Home page -> Most frequent 5 Alerts -> select any box to left of
"Signature" column. Results in error: "No alerts were selected or the
DELETE was not successful".
Example - drilling down to any column in alert listings results in
database error
Home page -> Most recent 15 Unique Alerts -> click on any item in "Total
#" column. Results in error: "Database ERROR:Database ERROR:You have an
error in your SQL syntax; check the manual that corresponds to your
MySQL server version for the right syntax to use near '-50, 50' at line 1"
Restarted all services, cleared browser cache, rebuilt alert database,
tried 'Repair Tables' option on Maintenance page.
