150443 - Viewing CSS Style Rules on a quote <Q> crashes mozilla

Status: VERIFIED DUPLICATE of bug 141022

(Other Applications :: DOM Inspector, defect)

Description

[Esben Mose Hansen]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1a) Gecko/20020609
BuildID:    2002-05-30 aka mozilla 1.0

Not much else to add. It happens in trunk builds and 1.0. I havn't tried Windows
yet, but I will next time I boot windows.

BTW: It seems to me that its in the JS component that mozilla crashes(!). I
didn't think that was possible.

Reproducible: Always
Steps to Reproduce:
1.Open the DOM inspector
2.View attached testcase, or apparantly any page with a <Q> tag
3.Expand the document tree and select the Q node
4.On the upper right window, select "CSS Style Rules."

Actual Results:  crash

Expected Results:  The style rules, and especially no crash :O)

First 20 lines of a stack trace.

Attachment: A very simple testcase, added for your convenience :-)

Adding appropriate keywords. 

I'll go test the Classic theme; if I don't write other comments the crash also
occurs for the classic theme.

sounds the same as bug 141022 'DOM Inspector crash if "CSS Style rules" is
selected on element matching no rules' and has the same stacktrace.

marking dupe.  reopen if you disagree

Guess you're right. Don't know why I didn't think so when I filed it. It even
has a patch, so I guess I'm in lock :-) Might as well VERIFY it.
