306084 - Move Tab to New Window crashes when only one tab is open [@ objc_msgSend]

Status: RESOLVED FIXED

(Camino Graveyard :: Tabbed Browsing, defect, P1)

Description

[Mike Marco]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b4) Gecko/20050826 Camino/0.9a2+
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b4) Gecko/20050826 Camino/0.9a2+

When moving tabs to a new window using the relevant context menu option, and
only one tab is open, the browser crashes. (Using the feature with two or more
tabs open works as expected.)

Reproducible: Always

Steps to Reproduce:
1. Make sure that "Always show tab bar" is enabled in Preferences and that only
one tab is open.
2. Control- or right-click the tab.
3. Select "Move Tab to New Window" from the resulting context menu.

Actual Results:  
Browser opens contents of tab in new window, but then immediately crashes.

Expected Results:  
The browser should not have crashed, or the option to move tabs into new windows
should be disabled when only one tab is open. (Seems a little silly that it
would even be allowed in the first place.)

I see this too, recent trunk build.

Shouldn't we just not allow this?

And does this only happen on the trunk or on the branch as well?

Fixed on trunk and branch.
