486818 - Thunderbird/Lightning freezes upon startup with multiple CalDAV

Status: VERIFIED DUPLICATE of bug 390036

(Calendar :: Lightning Only, defect)

Description

[Wim Bos]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.8) Gecko/2009032609 Firefox/3.0.8
Build Identifier: Lightning 0.9 with Thunderbird 2.0.0.21

I have multiple calendars under my Google account and I have set them up as CalDAV. Upon setup everything goes fine. Once you restart Thunderbird, the application appears to hang (processor utilization peaks at maximum).

Reproducible: Always

Steps to Reproduce:
1. Setup your Gmail account using IMAP
2. Add multiple Google calendars using CalDAV
3. Restart Thunderbird
Actual Results:  
Thunderbird/Lightning application freezes upon startup. Sometimes it does not load any calendar information at all, sometimes it loads some calendar information and then freezes and sometimes it goes trough without issues.

Expected Results:  
No freeze, just a normal startup.

When setting up the multi CalDAV setup in Sunbird, the issue does not seem to appear => Seems to be Thunderbird/Lightning specific.

Might be a duplicate of Bug 390036. Are both IMAP and CalDAV using a secure connection?

Indeed, it appears to be the same issue
