errors on uninstall "Notice: Trying to get property of non-object" [#1768528]

after un-installation of latest dev version I've got message:
" Removed G2 Glossary variables
The selected modules have been uninstalled."

but below some other errors have appeared, are they somehow related to G2?:

This does not appear to be directly related to G2:

The first message confirms that G2 removed its own variables
The second confirms that all the modules you choose to uninstall were indeed uninstalled
The error messages after that seem to imply that the entity information is no longer current

Did you try clearing cache (drush cc all, or use "clear all caches" in the Performance screen) ? And if so do you still get these messages once the cache has been cleared ?

You also appear to have a number of core and non-core modules enabled. Could you provide steps, starting from a clean core install, to reproduce the problem, to help diagnose what has been happening ?

If I clear cache after errors, they disappear.
Does it mean that errors are not serious?

I have very old installation with many modules and content, so I think it would be difficult to track all changes after fresh install to get these errors.

Exactly :-) They show some module does not refresh the entity schema before some operations. Once you clear cache, it is rebuilt and the entity and field info is updated.

Note that no module, including Classified Ads, deletes its fields and nodes upon uninstall, so if you have ad nodes, you must delete them before uninstalling the module.
