Summary: REGRESSION: Opening multiple bookmarks in tabs causes
assertion in
WebDocumentLoaderMac::decreaseLoadCount(unsigned long)
Product: WebKit
Version: 522+ (nightly)
Platform: Macintosh
OS/Version: Mac OS X 10.4
Status: NEW

AssignedTo: webkit-unassigned at lists.webkit.org

Summary:
Opening multiple bookmarks in tabs causes an assertion in debug builds in
WebDocumentLoaderMac::decreaseLoadCount(unsigned long).
Steps to reproduce:
1. Open Safari/WebKit.
2. Set up the following tab set:
http://bugs.webkit.org/buglist.cgi?cmdtype=runnamed&namedcmd=WebKit%20Daily%20Changes
http://build.webkit.org/
http://cia.navi.cx/stats/project/WebKit
http://trac.webkit.org/projects/webkit
http://lists.macosforge.org/pipermail/webkit-unassigned/
http://ln-s.net/IkX
3. Select "Open in Tabs" for the above tab set from the Bookmarks menu.
Expected results:
Safari/WebKit should open all the tabs and load all the pages without crashing.
Actual results:
Safari/WebKit crashes when attempting to open all those pages in tabs.
Regression:
This is a recent regression (last day or two) from ToT WebKit.
Notes:
Tested with a local debug build of WebKit r20202 with Safari 2.0.4 (419.3) on
Mac OS X 10.4.8 (8L127).
