Will also crash: - Smultron - Google Chrome - Safari

Same for FILE:///, filE:/// etc.

It doesn't have to be File:/// in particular, but rather any combination of caps/non-caps apart from all-lower.

Crashes Twitter client on retweet/quote-tweet (YoruFukurou)

Saw this in a tweet and when I hit the Quote Tweet it crashed my client. (ML 10.8.2)

Mail & iMessage

Try sending somebody a mail or iMessage with it. Crashes both Messages.app and Apple Mail, even when reading.

Truly embarrassing bug. Amazing that it hasn't been found before now - works in 10.8.0

By justin.may at Feb. 2, 2013, 10:32 a.m. (reply...)

This bug only affects Mountain Lion, not Lion or Snow Leopard...

Tried this on TextEdit.app on Mac OS X 10.6.8 and it doesn't crash.

Still, the quality assurance on Apple software has got lower than when Steve Jobs was still alive. The new iTunes 11 is horrible — it doesn't give the option of viewing the artist browser on All Music view, and does not remember the view setting on another intelligent playlist which has all my music on it.

Effects spotlight as well.

Do it in spotlight, and your entire menubar goes out for a second.

it will still crash. I could only get Console to stay open LM7805

NSTextView bug

If you create new project in Xcode and then add NSTextView in it, run the project and write File:/// in text view, your application will immediately crash..

By menelaus35 at Feb. 2, 2013, 8 a.m. (reply...)

Turning off those options doesn't work for all cases. If Console.app has system log with the string visible, it will still crash. I could only get Console to stay open if I caused enough messages to scroll the string out of view.

BBedit seems ok. I suspect it's not using system data detectors.

Hopefully, someone has filed an official developer bug report on this and it'll get addressed in 10.8.3 (though I think it might be too late). If no one here has by tomorrow, I might do one myself - far too late in the evening at the moment.

If you're stuck because you typed this and now your app is automatically crashing itself all the time, go to System Preferences, under Language & Text, Text, uncheck "Correct spelling automatically" and "Use symbol and text substitution". Both need to be unchecked.

Works almost everywhere

This is actually a feature. It allows you to shut down all applications before shutting down your Mac:

Crashes Finder if typed into a Finder search field (not Spotlight, though). Crashes Safari if typed into the URL bar. Crashes Mail if typed into the search field. Crashes iTunes when typed into the search field. Crashes system-generated keychain unlock prompts (typed into the "Name:" field) Crashes Reminders if typed into the search field. ...

More than just File:///

It's also not related to length, but the speed at which text is entered.

Typing File://aaaaaaaaaaaa very slowly does not cause a crash. Typing File://aa quickly does.

Video: http://f.cl.ly/items/1E3V2U1F2i1J1s441z0V/error.mov

Update: It's dependent entirely on the time between the second slash and the next character. Typing File://a very quickly causes a crash, File:/// slowly does not.

Update 2: A little different. Typing File://a slowly will not crash, but File://a slowly, followed by a new line, will.


Out of curiosity, have any of you tested on the latest beta?

By acfrazier at Feb. 2, 2013, 4:15 a.m. (reply...)

Yes. Crashes the latest beta.

10.8.2 here

I confirm too. It really crashes. Bug !

By chifuadrian at Feb. 2, 2013, 2:55 a.m. (reply...)

I tried this in TextEdit in Mountain Lion (10.8.2), crashed like a charm. As an extra bonus, I attempt to file a crash report: typing the description into the Crash Reporter UI caused Crash Reporter to crash and vanish.

Also, the previous note by 'shess' is better than it sounds: Every time Console.app opens, it now crashes. Excellent stuff.

If you want Console.app to work again, do this in Terminal.app:

sudo sed -i -e 's@File:///@F i l e : / / /@g' /var/log/system.log

This only seems to affect Mountain Lion

Reproducing the steps in Snow Leopard and in Lion do not result in any abnormal behavior ...

By nirk.niggler at Feb. 2, 2013, 2:22 a.m. (reply...)

Cool addendum: in Console.app, for the ReportCrash: line for an app which crashed this way, clicking "Open report" causes Console.app to crash with this crash.
