Hi Layale, It's always a good idea to include details about Koha set-up such as whether it is a package install or tarball install. Also are you on Ubuntu? I'm asking as it might help others troubleshoot the problem... because a quick Google revealed this http://koha.1045719.n5.nabble.com/Stack-Smashing-td3069232.html
Answer to whether you are using icu or not may also help others. Good luck, Arslan _______________________________________________ Koha mailing list http://koha-community.org Koha@lists.katipo.co.nz http://lists.katipo.co.nz/mailman/listinfo/koha
