524864 - pulldown AJAX menu crashes entire system

Status: RESOLVED INVALID

(Core :: General, defect)

Description

[rigel]

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.14) Gecko/2009090217 Ubuntu/9.04 (jaunty) Firefox/3.0.14
Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.14) Gecko/2009090217 Ubuntu/9.04 (jaunty) Firefox/3.0.14

I have replicated this bug with the gecko-using version of the Epiphany browser, so I suspect the bug is in gecko.

I can most reliably replicate the crash when I get a pulldown Subject:(typically subject, may also have happened with other fields but do not remember clearly) menu from the web "Lite" front end of a Microsoft Exchange 2007 server.

If I do not switch vterms within the first second or so of a freeze, it is unrecoverable. I can sometimes catch it and switch to a text vterm, and then restart gdm. even when unrecoverable, the mouse still works.

This happens on two separate machines with nvidia binary drivers (different versions), but I have not tested with the open source nv drivers.

Reproducible: Always

Steps to Reproduce:
1.begin new email in ms exchange 2007 server "lite" front end
2.start typing subject similar to previous subjects
3.crash
Actual Results:  
System monitor halts.
system crashes.

Expected Results:  
allowed to select previous subject line

Firefox/gecko is a usermode application and can not crash the system or the X server and it*s a bug in the system and not Firefox if Gecko triggers such a bug in your OS or the X-Server.

simple logic for every usermode application:
If the system crashes or freezes it's the fault of the system
If The X server crashes or freezes it's the fault of the X-Server
If a usermode applicatiuon crashes or freezes it's in most cases the fault of the application (exceptions are for example plugins in a browser)
