Description

Saving a package in the editor while there is a queued text mesh build will cause a fatal error because the build will execute during the save, and creating objects while saving is not allowed. This can occur during a manual save or an auto save.

This was reported on UDN as Case 00477787 and we have over 400 crash reports for it in the past month.
