Not obvious, but worth knowing:

"Smalltalk listBuiltinModules" gives a list of all internal plugins.
These are the plugins that are compiled into the main VM executable.

"Smalltalk listLoadedModules" give a list of all external plugins that
have so far been loaded. It is not necessarily a list of all of the
external plugins, rather it is the external plugins that have been
referenced by the image. The external plugins are loaded on demand,
and once loaded, are available for fast access to the primitives that
they provide.

If a plugin is compiled as a built-in module, and if it also is
compiled as a separate external plugin (Windows dll or Unix shared
library), then the external plugin overrides the primitive implemented
in the built-in module.

UUIDPlugin is usually provided as an external plugin, in part because
the UUID runtime libraries have been problematic in the past, see
for example http://bugs.squeak.org/view.php?id=7358. If a plugin like
this is causing problems, or if you suspect that it is causing problems,
then you can get rid of in on your computer by simply deleting the dll.

Or maybe, when the VM was busy to save my image (which, despite SSD, may take ten seconds from time to time). But I don't think any of these points should be a reason display "error no error".
