Description patrick 2004-05-11 19:17:28 UTC
Version:            (using KDE KDE 3.2.2)
Installed from:    Debian testing/unstable Packages
OS:                Linux

When trying to preview a posting (prior to submitting it) on www.debianforum.de I can reproducibly crash konqueror with the following backtrace (Dr. Konqi assumes it is useless, but it looks halfway OK to me, especially as gdb comes up with the same backtrace, which I am including below):

-------- Start of Backtrace -------------

--------- End of Backtrace ---------------
As mentioned, Dr. Konqi comes up with the same backtrace, but says it is not useable, and deactivates the "Copy" and "Save" buttons...

Steps to reproduce:
1) You need an account on the site. Simply register one, or contact me by private mail, so I can supply you with a temporary test account.
2) Go to any thread in the forum, threads with more Replies (german: "Antworten") are better suited, as otherwise step 4 won't work.
3) Click on "Antwort erstellen" to create a reply. You are then presented with a form where you can enter a reply. Enter a few letters there (otherwise phpBB will complain that you entered no text).
4) *This step is crucial!* Below the big textarea, there is a summary of the current thread containing the last few replies in the thread. Scroll this field down a little bit, so the scrollbar is not in its topmost position (Not the main scrollbar of the window!). If I omit this step, konqueror won't crash.
5) Click on "Vorschau" (english: "Preview") and konqueror crashes with the aforementioned backtrace.

I can reproduce this 100% of the time.

Relevant packages installed on my system:
dreker@wintermute:dreker$ dpkg -l kdelibs4 libc6 libgcc1 xlibs libkonq4 libqt3c102-mt
ii  kdelibs4        3.2.2-2         KDE core libraries
ii  libc6           2.3.2.ds1-12    GNU C Library: Shared libraries and Timezone d
ii  libgcc1         3.3.3-7         GCC support library
ii  xlibs           4.3.0.dfsg.1-1  X Window System client libraries metapackage a
ii  libkonq4        3.2.2-1         Core libraries for KDE's file manager
ii  libqt3c102-mt   3.2.3-2         Qt GUI Library (Threaded runtime version)

Please contact me, if you need more information. I can also assist with a little gdb work, if this turns out to be unreproducible.

Please check for updated Qt packages
