Summary: ASSERTION FAILED: maxWidth >= 0 in
StringTruncator.cpp:109 in WebCore::truncateString()
Product: WebKit
Version: 522+ (nightly)
Platform: Macintosh
URL: http://www.network-drivers.com/drivers/53/53064.htm
OS/Version: Mac OS X 10.4
Status: NEW
Keywords: NeedsReduction, NeedsRadar
Severity: Normal
Priority: P1
Component: New Bugs
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: ddkilzer at webkit.org
Summary:
Opening a page in a background tab (via command-clicking) that opens a
pop-under window causes an assertion failure in a debug build of WebKit.
Steps to reproduce:
1. Open Safari/WebKit.
2. Make sure the "popunder" cookie for network-drivers.com is NOT set via
Safari preferences.
3. Make sure "Block Pop-Up Windows" is NOT set.
4. Command-click on URL: http://www.network-drivers.com/drivers/53/53064.htm
Expected results:
The page should open without an assertion failure.
Actual results:
The page causes an assertion failure and Safari/WebKit crashes on a debug
build.
Regression:
Not tested for regression with Safari 2.0.4 yet.
Notes:
Console output from assertion failure:
ASSERTION FAILED: maxWidth >= 0
