669801 - folder pane and thread pane comes up empty on startup

Status: RESOLVED DUPLICATE of bug 658534

(Thunderbird :: Folder and Message Lists, defect)

Description

[David :Bienvenu]

Attachment: proposed fix

I've gotten into a state where the folder pane is empty on startup. Nothing too useful on the console, just that .tree is not defined. But wrapping the loading of the folder pane json fixes it for me.

I don't know what causes the error, and I don't see anything useful in the logging, but there are a lot of errors.

I may be able to figure out a way of causing the corruption, but for now, I just want to survive it.

I've seen this in the TB 6 builds as well I believe, so we're going to want this on branches.

My main thoughts about this were potentially incompatible add-on (lightning?) and safe-mode seems to get out of the error state - probably because we're resetting the chrome caches or the json file or something.

I've disable all my add-ons because of that. And I wasn't using lightning (so it's not the culprit).

My suspicion is that this happens when you close the 3-pane window before other windows, and closing the other window makes the app shut-down. For some reason, the compose window was not sufficient to reproduce this, but the address book window was (i.e., address book window is last to close).

this patch isn't right, and I think it was coincidence that the run I did after the patch worked.

I've had it a lot when the add-on manager was open.

I ran into this today when trying to use 3.1.12 on a profile that I had been using with nightlies. Many extensions. Safe mode made it usable.
Probably not worth eliminating extensions as a cause, because of the limited life of 3.1.x ??
I can reproduce it every startup.
gFolderDisplay is null Plus other errors.

A PIA for regression testing.

I believe this has the same root cause as bug 658534, which has a patch.

[Wayne Mery (:wsmwk)]

I've seen this only recently. It started after I used profile manager and safe mode. Fairly reproducible. agreed, rather a blocker for testing

Deleting the fastload cache (in app data/local/Thunderbird/Profiles/<profile dir>/Startup Cache/StartupCache*) fixes this for me as well (as a work around)
