User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:12.0a1) Gecko/20111225 Firefox/12.0a1 SeaMonkey/2.9a1
Build ID: 20111225003005

Steps to reproduce:

Upgrade SM to latest nightly on Dec. 24th and start it


Actual results:

No mail was filtered - turned out that all filters had disappeared from the message filter dialog. msgFilterRules.dat was empty except for version and logging ("9" and "no" respectively).
Happened again with trunk from 25th - my newly created filters were gone again...


Expected results:

Filters should have stayed in place...
Severity: normal → blocker
Priority: -- → P1
wfm with Mozilla/5.0 (Windows NT 6.1; rv:12.0a1) Gecko/20111225 Firefox/12.0a1 SeaMonkey/2.9a1

My single message filter is still there.
Severity: blocker → critical
Priority: P1 → --
Ah, yes, sorry. This is Linux.

Furthermore, I have discovered that if I add a new rule, then try to add another, the second one replaces the first...
In the same time frame 
- I've lost filters as noted in bug 713253. 
- the reporter of bp-7a462531-f732-415e-942d-665e12111225 also lost filters. his last message to me ...

"I had the profile window open when I loaded this
12.0a1. It appears that it over wrote the existing msgFilterRules.dat
or erased its contents when Thunderbird loaded. The actual file is empty
but the 'message filters' (loaded into memory?) still show in the GUI
and they continue to function as written until I close Thunderbird. Or
it crashes and closes itself. Evidently it then reads the empty file. The GUI appears to allow me to add filters but when I close the window and reopen it it is empty."

Hmm... On the webpage <http://harthur.github.com/mozregression/> it says  mozregression --app=thunderbird. Note the two dashes. That did not work.

However that fails with an error. If I knew how to add an attachment here I would so I will put it here. Please feel free to copy it here.

May I, since this is file-based as opposed to something with sqlite, and since it's apparently easy to hit a code path that zeroes the file, that someone institutes a "copy to .bak, then write the new file" thing, as it's apparently done for sessionstore.json, that we've had problems with before, which I guess is the reason for making backups in-app as opposed to relying on the user to have a backup mechanism in place?
Thanks for finding the cause David :(

aceman, no problem.
I must be more careful next time.
I guess that is the more proper flag to set.
