Version: (using KDE 4.1.3) Installed from: Debian testing/unstable Packages Konqueror crashes when some strings are passed to alert without quotation mark. I think it is caused by some special characters that I used. It must generate JavaScript error but not crashing the whole application. This example crashes konqueror when the text "Crash me" is clicked: <div onclick="alert(http://78.90.76.55/);">Crash me!</div>
Confirmed, debugger crash
Here using: Qt: 4.4.3 KDE: 4.1.86 (KDE 4.1.86 (KDE 4.2 >= 20081221)) kdelibs svn rev. 901624 / kdebase svn rev. 901624 on ArchLinux x86_64 - Kernel 2.6.27.10 I can reproduce the crash using the testcase HTML when the JS Debugger and Report Errors are enabled.

I am wondering: did all of you folks turn the debugger on yourselves, or was it perhaps on by distro defaults (which would be very bad...)? (will hopefully commit a fix for this today)
I turned it on for one of my own pages and forgot it was enabled...

(In reply to comment #10) > I am wondering: did all of you folks turn the debugger on yourselves, or was it > perhaps on by distro defaults (which would be very bad...)? I don't remember turning it on myself (although I used it a long time ago), so I guess that in Debian it was the default at some point (I just copied my configs from KDE3 to KDE4). Currently the "Defaults" button turns it off.
SVN commit 926127 by orlovich: Fix debugger crashes during parse errors. In particular, it means reportSourceParsed can't rely on there being an AST; and ditto for reportException. Also fix the code to report the top-level parse errors to the debugger; and adjust the debugger UI to handle these cases properly, by just displaying the code (and not getting confused trying to stop non-running code) BUG: 175578 M +15 -5 khtml/ecma/debugger/debugwindow.cpp M +5 -0 khtml/ecma/debugger/interpreter_ctx.cpp M +2 -0 khtml/ecma/debugger/interpreter_ctx.h M +7 -4 kjs/debugger.cpp M +2 -1 kjs/debugger.h M +1 -1 kjs/function.cpp M +1 -1 kjs/function_object.cpp M +9 -4 kjs/interpreter.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=926127
