Mail crashing when importing .mbox files

Question

I am trying to import .mbox files - exported from Entourage - into Mail on another users' computer running 10.5.2. I had no trouble doing this on my computer - twice before (also running 10.5.2). Mail crashes every time I click on the Import Files button.
Any ideas of what may be going on? I've deleted the To Do list items - per another suggestion I've read on the boards.
Any help would be greatly appreciated!
Thanks,
Brian

I have had a similar problem importing large mbox files from an O2M conversion (a Windows app to convert Outlook data to Mac friendly files). Some mbox files would not appear available to import. Larger mbox files would crash Mail upon import.
I tried importing the mbox files into Entourage first which seemed to help a lot, but Mail would still crash on import in most cases. My solution was to split the large mbox-generated folders inside Entourage before importing into Mail from Entourage.
It seems to me that the consistent issue here is simply that Mail chokes on 'large' mbox files (anything over about 500MB in my case). It takes forever to move all these emails around and import them this way but it seems to work.
I sure wish Apple would make their import routines more roubust.
