Anything Goes - Can you crash X?

Post subject: Can you crash X?
The Berlin wall was erected 50 years ago. There's an exhibition "Hinter der Mauer" about the village Klein-Glienicke. It has a website also with some press material, a.o. photo's. Most photo's are ok but one in particular is 'possessed'.

Best case: my browser (Iceweasel 5.0) flickers and comes to rest after a few seconds with a black page.
Medium case: X restarts, I'm at the desktop log-in prompt and my 2nd monitor needs to be switched off and on to bring it back.
Worst case: I save the pic and then open it in Iceweasel, system locks and I need the sys-req combinations to reboot. Opening the pic in Konqueror or Gwenview is no problem.

Want to try? Save your work, surf to
      Code:
http://www.hinter-der-mauer.de/presse/downloads
Under "Fotos" you can view pictures of the wall surrounding the village. The problem picture is "Doppelmauer am Waldrand".

Let me know how you fare.

iceweasel 7.0a2 with a single monitor (and no KDE) has no problem with the images…


P.S.: "Nobody has the intention of building a wall"

No problem with anything on that page period or anything I throw at it, with my default browser 8.0a1 (2011-08-12) (firefox nightly)

No problem on a 32bit Laptop. Interesting photo. Maybe your browser does not like the expansive metadata which is in this picture (I have never seen anything like that ... e.g. description in Korean!). The other pictures are cleaner.

Hallo CaesarTjalbo,
no problems with iceweasel 5.0, 32 bit on my laptop.
Greetings,
Jörg
P.S. Zijn wij de enige NL leden bij Aptosid?

Post subject: Re: RE: Re: Can you crash X?
So it's an issue that's not exclusive to my setup (64-bit, Nvidia proprietary driver). The issue of the 2nd monitor going dark may have to do with a setting in X that switches it off when an application wants to go really full-screen, like a game that doesn't run in windowed mode.

It's all a bit too borderline to submit a bug report, especially seeing that users of development versions don't seem to have this problem. But you can imagine it's disturbing that some seemingly innocent content on the web is capable of killing my desktop, not just the application I use to access it.

Good find! I've had Iceweasel complain before about a picture with errors, a picture which could be viewed without complaints by another program.

They're fairly wide-spread. The actuality of the anniversary, the exposition and the curious circumstance of that village make it all newsworthy. I got the link through the BBC website but that particular village was also on the TV news here in the Netherlands.

I cannot confirm this problem. Everything works ok on 5.0 IW, 64 bit, nouveau.

Maybe an add-on is causing problems. Try the pic running iceweasel in safe mode (i.e. without addons):
      Code:
iceweasel --safe-mode

Nope and I use add-ons sparingly. Iceweasel tries to go full-screen, at least that's my impression because the flickering is over the entire screen (while my browser is smaller).

So in one tab i'm typing this, in another tab I've that pic (a black square). Went to that tab once, flicker again, after that the pic seems in the cache. It's repeatable but at least it doesn't throw me out of KDE anymore. No errors on the CLI.

edit: not so. Went to the tab again and found myself then on the log-in to KDE with my other screen dark (but seemingly receiving input according to the led).

I had no problems opening all photos in iceweasel. (64bit)

If you have problems with iceweasel, try to purge and reinstall all iceweasel packages. Also delete all *.mfasl files (maybe there is only XUL.mfasl) before starting iceweasel. You find this GUI-caching file in you iceweasel/firefox-profile.

No problems with "Chromium 15.0.838.0 (Developer Build 94616 Linux) Debian unstable" from towo's repo.

And I'm totally blinged-out with Chromium extensions (63 at the moment).

Post subject: RE: Re: RE: Re: Can you crash X?
FWIW, I had a problem with it too. (64-bit, Nvidia proprietary driver, Debian/Aptosid current Iceweasel, single monitor.) The screen flickers for a while and then, after killing Iceweasel, all graphics on X become corrupted. Restarting X did not solve the issue and I had to reboot...

On IW/FF I have 30 extensions and no problems running them all Smile
