           Summary: regression - crash when opening multiple tabs, also
                    crash loading nytimes.com
           Product: WebKit
           Version: 522+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: Blocker
          Priority: P1
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: glenn.marshall at objectdevelopmentlabs.com


1.  Set preferences so a background tab is opened when flower-click is pressed.

2.  go to nytimes.com (do the free registration so the nytimes.com server sends
you comparable data to what I receive), scroll down to the body where there are
a large number of links physically close together

imagine that all of these links are extremely interesting and that you want to
read all of them

3.  start to flower click (open in background tab) on 25 links (25 will appear
on a single page, so scrolling isn't required).  

Be reasonable - after clicking, move the cursor off the link, wait until it
switches from a hand to a pointer before moving to the next link and clicking
(this isn't a concurrency stress test).

Also, don't release the flower key too quickly, wait for,  say, 1/2 second or
so.  If you release too quickly, the flower key press won't be detected, and
link will be opened in the current tab 

(another, bug, albeit lower priority, in my view - the fact that the flower key
was pressed isn't attached to the event, but rather needs to be read by the
program when it processes the event, forcing the user to wait and needlessly
limiting "mouse ahead"),

4.  once all 25 are up, click to the second tab and choose print to get rid of
the graphics.  Repeat for all visible tabs, excluding the first (for me, this
is 9 tabs).

-----------------------------------------------------------------

Results for me:

attempt #1 - crashed on load

attempt #2 - crashed on first click

attempt #3 - managed to click on 25 tabs, but when I clicked the chevron on the
right end of the tab bar, it crashed.  I noticed that all titles were filled
except the last that had a title of "Loading ..." or something to that effect.

attempt #4 - crashed on load

attempt #5 - crashed on load

attempt #6 - crashed when clicking the 25th tab

crashlogs attached.  Note that they are in reverse order.

--------------------------------------------------------------------

Notes:

1.  I experienced a similar behaviour at workopolis.com - enter keyword scrum.
You will get around 30 results.  Attempt to open each in a background tab.  I
tried this something like 7 or 8 times, and always got a crash.  

If you get an error saying something about a query failure, follow the
instructions, hit the back button and retry (I got this on the first attempt
several times).  You will, worst case, on the second attempt, get the results.  

All of crashes occured when actually loading tabs, unlike nytimes.com.  I never
got beyond 10, however, before crashing.  I have not attached the crashlogs for
this, but can, if helpful.

2.  I tried the identical test in Safari for nytimes.com:  I loaded 25 tabs in
the background, then, for the 9 that were visible clicked print.  This worked
without crashing.

I repeated this 3 times in Safari to be absolutely certain - all 3 times worked
without a crash.

(will add crashlogs next)
