Crash on save/export

Question

We have recently installed a new editorial system (Newspaper) and started using InDesign 5.5 (7.5.2.318) extensively.  However the editors keep having crashes happen to them when they save or export a document. 
The error message I'm seeing in event log is similar to the one below:
Faulting application indesign.exe, version 7.5.2.318, faulting module text.rpln, version 7.5.0.142, fault address 0x000c9b44.
I am by no means a InDesign expert so I'm kind of grasping at straws.  I think part of the issue is that the files being put into their document are to large (anywhere from 75megs down to 15 megs in size; multiple files being put onto a page), but am not sure. 
Does InDesign create an event log entry every time it crashes (if it does then there's some exageration going on!)?
I've looked high and low for some information on tuning InDesign for better performance, but haven't found anything. 
Are there some generic things I should check?
By the way we are on Windows XP 32bit, 4 gigs of ram, Quad Core
Thanks in advance for your time,

When you have third party plugins and crashes, the first suspects are generally the plugins. Do you also use a font manager?
Please see Guide to Interpreting InDesign Crash Reports | InDesignSecrets for directions on finding the crash log you need and how to interpret it (or you can post the log on Pastebin.com and put a link to it here, and John will eventually try to read it for you).
