85866 - persisting outliner "hidden" state causes crash

Status: VERIFIED DUPLICATE of bug 83906

(Core :: XUL, defect)

Description

[Robert Ginda]

update your extensions/venkman directory, start venkman, and use the "column
picker" control from one of the outliners to turn off a column.  (I tested with
the "scripts" column from the file list, and the "filename" column from the
stack list.)  Exit mozilla, and restart.  Launching the debugger will crash with
the following stack:

Dup of 83906, use collapsed so the frames aren't destroyed.
