Do not use any builds from November 19th, 20th, or early part of the 21st – it can destroy irrecoverably any armature file used.
Also, please delete any builds you are personally providing to the community from these dates.

Hi,
All test builds made between 2006/11/19 00:07:32 CET and now will mess up Armatures, if you enter editmode once. That’s an unrecoverable error, so you might consider to remove such testbuilds to prevent damage to animation files.
