Sometimes helping someone fix a problem leads to unexpected discoveries.  I had a client who was experiencing repeated crashes in Visio 2010.  We found numerous articles discussing crashing in Visio 2007 and 2010.  Unfortunately none of these solutions were of any use in our case (for instance, Vista or Win7).

The suggestions range from running Visio as an administrator (we were) to disabling add-ins and macros (none were enabled).  I was considering removing Visio using Revo Uninstaller and reinstalling it afresh.  In the end I didn’t have to do this.

The user was also running an application called Lingoes on this (virtual) machine.  It turns out this combination of applications was causing a conflict.  Once we uninstalled Lingoes from that machine Visio stabilized and crashed no more.

If you are interested in language you may want to take a look at Lingoes.  It seems like a pretty robust translation and dictionary software.  Just don’t expect it to play nicely with Visio.
