514784 - "ASSERTION: reflow state computed incorrect width" with xul:scrollbar

Status: NEW

(Core :: Layout, defect)

Description

[Jesse Ruderman]

Attachment: testcase

###!!! ASSERTION: reflow state computed incorrect width: 'reflowState.ComputedWidth() == size.width - reflowState.mComputedBorderPadding.LeftRight()', file /Users/jruderman/central/layout/base/nsPresShell.cpp, line 7068

###!!! ASSERTION: non-root frame's desired size changed during an incremental reflow: '(target == rootFrame && size.height == NS_UNCONSTRAINEDSIZE) || (desiredSize.width == size.width && desiredSize.height == size.height)', file /Users/jruderman/central/layout/base/nsPresShell.cpp, line 7085

This might be the same as bug 388254, but it's hard for me to tell since that bug has a convoluted set of steps to reproduce rather than a reduced testcase.
