New webkit crash

[Jack <ostroffjh sbcglobal net>]

In trying to track down my problem with webkit hanging on certain  
emails, I recompiled webkit-gtk (1.6.3) with debugging on.  Now, when I  
try to open any HTML message, I get a crash with

ASSERTION FAILED: m_currentItem
Source/WebCore/loader/HistoryController.cpp(111) : void  
WebCore::HistoryController::restoreScrollPositionAndViewState()
Segmentation fault


I have not yet run under gdb to get a backtrace, but I won't have time  
for that until later.  In the meantime, if anybody has any thoughts,  
please let me know.

(Building webkit-gtk with debug on takes over 5GB of disk space, and at  
times ld uses almost my entire 3GB RAM plus around another GB of swap,  
so it's a non-trivial exercise for me.)
