Description kavol 2009-11-02 13:17:04 UTC 
Application that crashed: konqueror
Version of the application: 4.3.2 (KDE 4.3.2)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.30.9-90.fc11.x86_64 x86_64
Distribution: "Fedora release 11 (Leonidas)"

What I was doing when the application crashed:
The subject says that all. I've tried to log in at https://cz.mbank.eu but I mispelled the password. For a short while there was displayed an information like "cannot perform the operation - already done" or what, it crashed too fast, I couldn't catch it all.

Note that unlike the similar bug #176538 says, I was NOT trying to use the javascript debugger, I just wanted to use my bank account as usual and done hundreds times before (without mispelling the password :-)

Comment 1 kavol 2009-11-02 13:21:48 UTC 
ok, this seems to be reproducible well

after unsucessful attempt, a dialogue box says "Akce je již provedena." ("Action performed already") and after clicking OK, Konqueror crashes (I must have hit Enter twice or what, why the dialogue disappeared so quickly at the first attempt)

Comment 4 Dario Andres 2009-12-17 19:14:46 UTC 
I could reproduce the bug here using:

Qt: 4.6.0 (kde-qt master commit 784477685913781462c426e99605546a4beaf3a4
        Date:   Tue Dec 1 19:17:20 2009 +0100)
KDE Development Platform: 4.3.82 (KDE 4.3.82 (KDE 4.4 >= 20091211))
kdelibs svn rev. 1063229 / kdebase svn rev. 1063229
on ArchLinux i686 - Kernel 2.6.31.6

Steps to reproduce:
---

- Download the testcase file I attached in comment 3 (it doesn't seem to work if trying to reproduce the crash with the online attachment)
- Open Konqueror
- Enable the Javascript "Debugger" and "Report errors" options
- Restart Konqueror and open the testcase file page
- In the two input fields add random strings (I used "aaaa" for both fields; I don't really know if there is a relation or if the strings have some special requirements)
- With the second inputbox focused, starting pressing and releasing the Enter/Return key continuously.
The mentioned error dialog of the webpage will be shown and close several times (seems instantaneous, as we are pressing Enter a lot of times in a quick sucession)
- If Konqueror didn't crashed after ~ 10 seconds ~ of pressing Enter, stop pressing it, and when the last error dialog is closed, Konqueror will crash.

I have disabled the cache and tried with other different settings combinations which may be related or not, if you need more information just ask me.

Comment 5 kavol 2010-02-18 11:35:17 UTC 
the bug is still present in KDE 4.4

but now the behaviour with the real site https://cz.mbank.eu/ is a bit different

it does not matter if I use correct password or not, it crashes reliably (on each try) if I submit the login form by pressing the Enter key - submitting via mouse click does not lead to crash and I can use the site without any problem

Comment 6 Andrea Iacovitti 2013-11-15 22:51:29 UTC 
I don't get the crash either using online site or following the steps at comment #4 using testcase at comment #3.
Tested with KDE 4.11.3
