Reported 2008-03-18 20:36:35 PDT
Reopen All Windows From Last Session causes crash Open some webpages in windows and tabs. Quit Webkit. Open Webkit. Select the History:Reopen All Windows From Last Session menu item. CRASH! This problem arose sometime recently within the past week's nightly builds. r30966 and earlier builds are OK and do not have the problem. The problem was introduced after the r30966 build. I could not pinpoint which build introduced the problem. Several recent builds contain this bug. r31132 is the current build and continues to have the problem.

(In reply to comment #3) > I can't seem to reproduce this with ToT. Tested again with r31157 build, and was able to reproduce the crash. But there is a difference depending on Preferences or sequence of events before Reopening All Windows From Last Session. Using these preferences: Safari:Preferences:General:New windows open with: Empty Page Safari:Home page: (is blank) Open some webpages in windows and tabs. Quit Webkit. Open Webkit. Select the History:Reopen All Windows From Last Session menu item. CRASH! To prevent the crash, try the following: Open some webpages in windows and tabs. Quit Webkit. Open Webkit. Open a new window and browse some webpage. Select the History:Reopen All Windows From Last Session menu item. This works OK.

recent builds are not stable on my system. because I open many windows and tabs when I browse, the ability to Reopen All Windows from Last Session is vital to recover from any browser crash. due to the frequent crashing and general instability of recent builds, this bug (#17933) makes the browser completely unusable for me.
