427647 - Crash [@ nsAutoScrollTimer::Notify] with collapsing selection, drag selecting and reload

Status: RESOLVED WORKSFORME

(Core :: DOM: Selection, defect)

Description

[Martijn Wargers (dead)]

Attachment: testcase

See testcase, which crashes current trunk build when the window starts scrolling  during drag selecting.

This regressed between 2007-11-21 and 2007-11-25:

I think a regression from bug 368760.

I don't think this should block.

Attachment: testcase2

This testcase crashes much more reliably when drag-selecting. In fact, it's crashing every time I try.
I was actually trying to minimize a testcase that was crashing like bug 421839. I'm guessing that bug is basically the same as this bug.

This is worksforme in current trunk build. I guess this might have been fixed by bug 421839.
