%%%Blender 2.63.10
Tested on Built r47656 and official release
Mac Os X (10.6.8)

Add a plane with some basic hair particle system
Add another object and add a ParticleInstance modifier for this object ; fill the "object" field then select "Create Along Path" (the bug occurs only with this option)
Now turn off the Particle System visibility on the viewport.
Save your file.
When you try to reload it Blender crash.

%%%I tried to redo your steps with svn r48832 and 2.63 (not "a" though), in linux and wasn't able to reproduce this.

Does this look like what you were describing? http://www.pasteall.org/blend/15047%%%

%%%I'm now on r48717 and the bug still occurs.
I tried your file, it works just fine but you hide the instance not the particle system.
I upload two files as a simple test.
The first is the basic scene, with a particle emitter and an instanced object ; no problem with this one.
The second is nearly the same but, in this one, the particle system is hidden ; I can't re-open it.

%%%Ah my bad, I hid the wrong one :)

Sure enough, soon as I switched it around I got the crash. Also, it seems you forgot to attach the files to your comment (it's a quirk of the tracker that you have to attach the files at the same time you comment IIRC).

I am attaching my crash file for you, along with a back trace.

Thanks for the report!%%%

%%%Fixed in SVN. Note that disabling the hair (particle) system makes it unusable for the instance modifier (no transformation of instances). There's no good solution for this atm, but at least won't crash.%%%
