Status: RESOLVED EXPIRED

(Firefox :: General, defect)

Description

[Michal Ceresna]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050513 Fedora/1.0.4-1.3.1 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050513 Fedora/1.0.4-1.3.1 Firefox/1.0.4

1. open the attached png image
2. right-click it at choose set as wallpaper

The browser code crashes.

After tracking it down, it crashes in nsGnomeShellService.cpp,
due to some bug in nsIImage implementation.
It seems that for all calls to GetAlphaBytesPerRow, GetAlphaData
nsresult is not NS_OK


Reproducible: Always

Do you have a stacktrace or a talkback id?

Comment 3

[Frank Wein [:mcsmurf]]

Possible dupe of Bug 264586 (also it seems no alpha is involved there)?

reproduction information if you have it.
