Status: RESOLVED WORKSFORME

(Core :: Widget: Gtk, defect)

Description

User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:2.0b7pre) Gecko/20101004 Firefox/4.0b7pre

I selected a number of emails to move from one folder to another, started dragging them to the folder, but missed. While the drag placeholder was still animating back to the messages I tried to start the drag again which triggered the crash.

Will, any chance you can try trunk source?
3.1.4 is the last crash seen in crash-stats.
