1069332 - [e10s] with autostart=true crashes Zimbra web-mail client during File Attachment file-selection

Status: RESOLVED DUPLICATE of bug 1067351

(Firefox :: General, defect)

Description

[Robert M. Enger]

hi:  I am using 35.0a1.  Problem is present through 2014-09-18 version.
I use the Zimbra web-mail client.  It has worked fine for a long time.  
It works great with Nightly in normal mode.
If I activate e10s (autostart=true) and attempt to attach a file to a message, then Nightly fails with an "opps this is embarrasing" <unable to present page, or some such error>.
 
When the add-attachment screen is presented, and I hit the 1st button, and select a file and click attach: wammo!
This is repeatable.  It happens with multiple files.
It happens whether Zimbra is operating in old HTML more of newer AJAX mode.  
To work around, all I did was set "autostart=false" and re-start FF.

Other than this, I have not have any problem with e10s mode.  I've had it active for multiple days and hadn't seen any error messages or misbehavior.

NOW, I cannot repeat it.  
I decided I wanted to give you folks a picture of the crash page.
So I turned e10s multiprocess back on, and went through the exact same procedure.
IT WORKED.  
Mind you it failed over and over and over before.  I even switched back and forth between HTML and AJAX mode, and tried different files as the attachment.

I have NO explanation for this.  The circumstances look similar (I even used the same destination address in my repeat test).

Maybe you should back-burner this complaint unless I can make it happen again; perhaps I can find some precipitating event or set of circumstances that triggers the behavior.

Sorry to cause you any trouble.
