1. Launch Messenger using -mail option
2. Click on Get Msg

Actual result: crashes occurs immediately

Expected result: It should not crash

This occurs consistently in IMAP. Pop sometimes works.

I've done a few other stack traces, they all look the same, except that
sometimes main_arena is not there.

it crashes without even clicking. Just watch the tooltip appear - move mouse
away - crash.

Comment 7

[scottputterman]

I checked in the fix for this.  I'm removing smoketest keyword and reassigning 
to pinkerton.

Pinkerton:  To reproduce this crash, get a linux build and then go to the file 
mailnews/base/resources/content/mailWindowOverlay.xul

Look for the button with the id : "button-getmsg".  In that button add: 
tooltip="aTooltip".  Then when you mouse over the button a tooltip should 
appear.  When you mouse away, the crash that alec mentions will happen.

marking nsbeta2 to fix if we want to have tooltips in our Beta2 product for 
mail.

This bug is fixed in the re-spin. I no longer see crash when click on New Msg or
Get Msg or mouse over toolbar. Scott, I am going to mark it fixed. If it is a
problem, please let me know.

reopening - let's just use this bug to track the tooltips part.

Comment 11

[Mike Pinkerton (not reading bugmail)]

what tooltip part?

Comment 12

[scottputterman]

the part where tooltips on toolbar buttons in the mailnews 3pane on Linux cause 
a crash.  In my comment from 11:17 I mentioned how to reproduce it.  We had to 
turn tooltips off due to the crash.  If there's something wrong with the xul, 
let me know and I'll fix it.  It works on Windows.
