See the code below and make two files of it: A weird bug.... If the select in the first file miss the / in the last option in first element, and you have selected something in the first select to make code fetch the other select from server using some "Ajax" like code and then select something from the second select... then Safari beta for windows crashes most of the time. If it does not crash right away, then just try to make some changes in the selects and then make sure you click the second select again.... Tested on Safari 3.0.3 on Win XP PRO. If I try this without the fetchHTML call on the first select then Safari does not crash. So it might have something to do with javascript..... Test the files below.... How do one make attachement here...??? That would be nice to be able to do......!!!!

(In reply to comment #0) > Test the files below.... > How do one make attachement here...??? > That would be nice to be able to do......!!!! In this version of Bugzilla, you may only attach files after creating the bug. See the "Create a New Attachment" link on the bug now. Does this still happen with a WebKit nightly build? http://nightly.webkit.org/ Could you attach a user.dmp file for the crash? http://webkit.org/quality/crashlogs.html Thanks!

Comment on attachment 15950 [details] crash dump file 2 This crash log is from a crash of mysqld.exe, not Safari.exe

Tore, I was able to reproduce the crash in Safari for Windows 3.0.3, but I haven't been able to make it crash when using a WebKit nightly from <http://nightly.webkit.org/>. Have you seen the crash when using a nightly, or only with the beta?

Since we haven't heard more about this issue in over a month and no one seems able to reproduce it, I'm closing as WORKSFORME.
