Segfault

When I go to Tools->Import->Wordpress in my WP configuration, I end up on a white screen. The log files reveal that I’m getting the following error:

server1 kernel: httpd[8187]: segfault at 00007fff6e0f3fec rip 00002b2c3cab3594 rsp 00007fff6e0f3fc0 error 6

The server is running PHP 5.2.8. Is my best bet to contact the host and ask them to upgrade to a newer PHP version, hoping that the problem will go away, or does anyone have a better idea? Unfortunately I need the import function badly, also I’d have no idea what to do if the host can’t get it done, or the upgrade doesn’t fix the problem. Thanks!
