If one tryes to grag-and-drop image for several times without actually dropping it in meaningfull place, segmentation fault occures and Mozilla (version 1.0RC1) shoots down.
If you are crashing in Mozilla the best thing you can do to help the developers fix your bug is to attach a stacktrace. If you're not building yourself you are not out of luck. Mozilla releases nightly and milestone builds with Netscape's Talkback (you can get latest build on: http://ftp.mozilla.org/pub/mozilla/nightly/latest/) Talkback should catch most crashes and offer to send in a crash report. Developers can retrieve that crash report and attach it to your bug report if you provide either the Incident ID (you can get it by running the talkback program from /components/talkback/). Thanks for your help in testing Mozilla and reporting bugs.
Likely dup of topcrash bug 81779, now fixed. Duplicates there mention same or similar way to provoke the crash: repeated drag/drop of images (bug 137186, bug 135628). Resolving as dup. Reporter: If you see the crash with builds from April 25th or later, please add comment. *** This bug has been marked as a duplicate of 81779 ***
