24735 - Printing causes mozilla to crash

Status: VERIFIED FIXED

(Core :: Printing: Output, defect, P1)

Description

[anantk]

Ok the following operations cause mozilla to crash consistently on my machine

-> Start mozilla
-> Go to bugzilla.mozilla.org
-> Select search for bug
-> Print to file setting the bottom and right margins to .50 (I use the file
/var/tmp/netscape.ps)
-> Once it's done printing do the exact same thing again on the same file
(/var/tmp/netscape.ps)
-> This causes the browser to crash with a segfault

Sorry my system settings are as follows:
Printer : Brother MFC P-2000 (Masquerading as a Laserjet II) Althought this
should not matter as I am printing to a file
OS Details : Linux 2.3.39, Debian potato
Print Filter : Magic filter ( This should also not matter as I am printing to a
file)

Looks like scrolling code. Assigning to blizzard. Was easy to reproduce on RH
6.1.

I was crashing last night printing www.cnn.com.

Comment 12

[shrirang khanzode]

I tried the steps as mentioned by the bug opener. ie printing to a file and it 
works fine in today's build. These same steps used to crash the browser earlier.

[Christopher Blizzard (:blizzard)]

Yeah, this is probably not the same bug.  I found a specific problem exposed
with those exact steps.
