309298 - Drag and drop of a file onto the Bookmarks Manager works inconsistently and can cause a crash [@ JS_GetPrivate][@ nsWindow::OnDragMotionEvent]

Status: RESOLVED WONTFIX

(Firefox :: Bookmarks & History, defect)

Description

[Robert Strong (they/them - no direct email)]

This is essentially the same as bug 269568 except it is for the Bookmarks
Manager. Here is the talkback incident id though talkback is seriously backed up
atm.
http://talkback-public.mozilla.org/talkback/fastfind.jsp?search=2&type=iid&id=TB9540134Q

To reproduce, try DnD of a local file onto the Bookmarks Manager's right pane
with Linux (tonight I am using slackware 10.1 and tested both gnome and kde - I
have also reproduced on other distros)... when I did this repeatedly Firefox
crashed, once it created a valid entry for the file, most often it did nothing,
once it created an invalid entry for the file with utf-16le encoding, and once
it created an empty entry. This doesn't appear to affect the Bookmarks Toolbar
which is probably due to not trying to validate the DnD data before the drop
occurs as noted in bug 269568.

The following message was reported repeatedly to the console even well after the
DnD operation had been completed (also explained in bug 269568.
(Gecko:3505): Gtk-CRITICAL **: gtk_drag_get_data: assertion `GTK_IS_WIDGET
(widget)' failed

What about this bug with current Firefox v2/v3 ?

I found nothing on crash-stats with signature nsWindow::OnDragMotionEvent nor  nsWindow::OnDragMotionEvent() for last 12 weeks.  Nor nsWindow::OnDragMotionEvent in top 10 frames of last 11 hours.  So if this crash still exists (I didn't attempt to reproduce) then it's not being reported.

so much has changed both in Places, in D&D and gtk code that I feel like there is nothing we can do today to find and address this.
I'm marking wontfix, if you don't agree feel free to reopen and comment on why you think it's still worth looking for it.
