Description Ronald Wahl 2012-04-29 17:01:08 UTC 
Description of problem:

Thunderbird 12 trashes mail when moving mail from the local UNIX mail spool. Most of the mails get lost. This is absolutely not acceptable!

Version-Release number of selected component (if applicable):
12.0-1.fc16.x86_64


How reproducible:
Always (even in safe mode with all add-ons disabled)

Steps to Reproduce:
1. Configure a local mail spool
2. send some (e.g. four) test messages to this spool (e.g. content "test" subject "test")
3. Get Mail in Thunderbird
  
Actual results:
Only one message is received instead of four. The mailbox file also contains only a single mail. In my case with specific messages Thunderbird mangles two mails together so that one email contains the header of the next email in the mailbox file.

Expected results:
Each mail should be received and displayed.

Additional info:
Downgrading to Thunderbird 11 fixes the behaviour. Is it possible to revoke Thunderbird 12 until this is fixed? I think this is really critical.
