Steps to reproduce:

Using the week view in Lightning 1.0b7
I tried to open an existing event on a remote Google calendar by right clicking and selecting open. I also tried to create a new event event by right clicking on a day and selecting "New Event"

Actual results:

When I create or try to open an event lightning hangs and both lightning and Thunderbird fail to respond. Thunderbird must be closed by using the ( x ) , resulting in a Force Close Message Box with the Message: "The window "Calendar - Mozilla Thunderbird" is not responding." Force Closing, exits Thunderbird down completely.

I am currently using the Latest Ubuntu 11.10 development release with all updates as of 9/29/2011as well as the latest Thunderbird and lightning release included.

Lightning event hang thunderbird 7.0.1 build information

Any error messages visible in Tools > Error Console?

How do you access your Google calendar? By using the Provider for Google Calendar extension? Or by using the built-in CalDAV provider?

Does this happens only with the custom Ubuntu builds? Or does it happen with the original builds from mozilla.org too?

I access my calendar using the provider for for Google.
I am using the Ubuntu custom build.

Thunderbird error console output

But not observed with TB7.0 LG1.0b7 on WinXP and DAViCal calendar server.

Since the last few Ubuntu 11.10 b2 / unity updates this error seems to no longer occur. It was consistently repeatable until mid last week; However, I am now successfully able to edit current events and create new events.

Ok, in that case I'll close this bug as WFM. If it re-appears, please do reopen the bug.
