752730 - Exception 0x80550013 [nsIMsgFolder.subFolders] location: "JS frame :: resource:///modules/MailUtils.js :: MailUtils_discoverFolders :: line 77" (Once a localized Tb 12.0.1 build is used, this exception is reported for each POP3 account upon each restart)

Status: RESOLVED DUPLICATE of bug 759237

(MailNews Core :: Backend, defect)

Description

[WADA:World Anti-bad-Duping Agency]

Build : Tb 12.0.1 release build.
Same in Tb 12.0.1 ja & Tb 12.0.1 de.

Once a localized Tb 12.0.1 build is used and localized special folder name is shown at folder pane, following error is always reported at Error Console for each POP3 account when Tb 12.0.1(any localization) is restarted using same Tb's profile.
> Discovering folders for account failed with exception: [Exception...
> "Component returned failure code: 0x80550013 [nsIMsgFolder.subFolders]"  nsresult: "0x80550013 (<unknown>)"
> location: "JS frame :: resource:///modules/MailUtils.js :: MailUtils_discoverFolders :: line 77"  data: no]

I couldn't observe error in message filter execution even though this Exception was reported. But this kind of exception shouldn't occur.

[Steps to reproduce]
(1) Use a Tb's profile(call ProfX) by Tb 11.0.1 en-US, in order to to bypass
    problem of bug 752423.
    Use View/Folders/Unified once and back to View/Folders/All, to avoid
    unwanted error messages related to smart folders.
    All special folders are shown in English name.
    No need to define message filter.
    Terminate Tb 11.0.1 en-US build.
(2) Start localized Tb 12.0.1 using ProfX. (checked with de & ja build)
    All special folders are shown as localized special folder name.
    Terminate Tb.
(3) Restart Tb 12.0.1 of same localization using same ProfX.
    Above exception is reported for each POP3 account upon any restart.  
(4) Restart Tb 12.0.1 of same or different localization using same ProfX.
    (checked with en-US, de, ja build)
    Above exception is reported for each POP3 account upon any restart.

Root cause seems "localized folder name is written in .msf file by Tb 12".

I could confirm the fix for bug 752423 does also fix this issue.

Oops! Accidentally removed dependency.

I'd suggest that try catch statements should be removed there.

Proposed fix

There are lots of ways getsubfolders can throw an exception, so I think we should leave the catch and logging in, and just mark this bug as a dup of the bug where you have a fix for this particular exception. If I'm misunderstanding something, please let me know...

Is there any relation to bug 751562 here?

It's the same error code, NS_MSG_FOLDER_EXISTS. I didn't think we could still return that error code, but there must be some path that does.
