[Koha] Label printing - it take too much time and Koha 3.00.01 stable crashes

Dear All I've installed koha 3.00.01 stable version on Debian 4.0 r7 Etch on an i386 p4 machine. Everything is running fine. But when I try to print the labels and barcodes from any template at /cgi-bin/koha/labels/label-home.pl, when I try to add items in some batch at /cgi-bin/koha/labels/label-item-search.pl?batch_id=1&type=labels the system does not respond for a long long time and my Koha system also crashed during this process. I've tried this on a couple of machines but the error is same. Can someone help me to fix this issue? The same problem is with my another friend. Ata ur Rehman Islamabad, Pakistan
