161517 - Tabbing off the last links crashes Mozilla [@ nsTypedSelection::selectFrames]

Status: RESOLVED DUPLICATE of bug 161444

(SeaMonkey :: General, defect)

Description

[Frank Burleigh]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.1b) Gecko/20020807
BuildID:    2002080704

Pressing the tab key while the last link is focussed crashes Moz.

Reproducible: Always
Steps to Reproduce:
1. visit the page
2. press tab five times (there are four links on this simple page)
3. observe moz crash

I classify it "major" because the browser shouold never crash. ;-)

confirming on linux build 2002080705.

works fine on linux build 2002080204.

Comment 2

[Jason Bassford]

Also confirming. (2002080704 trunk under XP.)

Note that this has nothing to do with the referenced URL.  Mozilla will crash
regardless of what page you're on once you tab past the last tab element.

Fastest method of reproducing: Open a blank browser window with Ctrl-T (or
Ctrl-N if you've set that preference to blank page) and hit Tab twice.  I get a
crash every time.

--------------------
Product ID  MozillaTrunk
Build ID 2002080704

URL visited www.library.uiuc.edu/lax
User Comments I used ctrl+N to open a new window, then pressed tab several times
to highlight the URL, which i wanted to change. it never highlighted so i
clicked to the right of the existing URL. that's when the browser crashed.
