User-Agent: Mozilla/5.0 (X11; U; IRIX64 IP30; en-US; rv:1.3b) Gecko/20030220 Build Identifier: Mozilla/5.0 (X11; U; IRIX64 IP30; en-US; rv:1.3b) Gecko/20030220 Tried to drag a group of messages from the server's Sent folder to the Sent folder in Local Folders; several messages had attachments. Only one message was moved. Then moved several messages individually with no problem. On trying to move the next one, the pane sizes in the Mail window flickered and settled with the left pane too narrow to read. When I tried to resize it, I found that mozilla had frozen. There was no response to any mouse clicks or key clicks in either Mail or the Browser. Had to use the Unix kill command and restart mozilla to send this message. Console window displays this error message: Gtk-CRITICAL **: file gtkdnd.c: line 621 (gtk_drag_get_data): assertion `widget != NULL' failed. Gtk-CRITICAL **: file gtkdnd.c: line 621 (gtk_drag_get_data): assertion `widget != NULL' failed. Reproducible: Couldn't Reproduce Steps to Reproduce: 1. 2. 3. It may be that the bug is in the flickering that sometimes occurs when going from one message to another, even without drag and drop. This flickering happens frequently but I hadn't seen it cause a crash before. The flickering seems to be related to the size of lines in the message or, perhaps, very long words, such as URLs.
I get this same error in mozilla 1.7rc1 and every version I've tried before it (several) when using a tablet. It may only be a problem when using a tablet, or it may be that the problem is simply more easy to trigger with a tablet. Sometime in the last 13 months, the problem seems to have moved down two lines in gtkdnd.c. Gtk-CRITICAL **: file gtkdnd.c: line 623 (gtk_drag_get_data): assertion `widget != NULL' failed. I'm not sure how to reproduce this problem. Some users come accross it frequently, and others not at all. I can only assume it's some small aspect of the way they use the table that makes it happen. This error does not crash mozilla, it simply stops mozilla from receiving any more input from any source. Keyboard, mouse or tablet. killing mozilla is then the only choice.
A potentially related error which I haven't seen as frequently (only once in fact) is... Gtk-WARNING **: invalid cast from `GtkSuperWin' to `GtkWidget'
