Bug 161603

I'm using svn 4.0 branch r802754. flash 9.0.119, also 3.5.8 debian sid.

Yep, crashes hard in both. I can't get a bt in gdb or valgrind. See below for what I did get.

Oh super annoying: some people got it to work:
nareshov: openSUSE 10.3 with KDE3 backport repo => 3.5.9, flash 9.0.124.0-0.1
foureyes779: Slackware 12.0, KDE3.5.7, flash 9.0 r115

And some not:
azuriel: crashed on kubuntu and gentoo for 3.5.9, flash 9.0 r64

Lots of these (from valgrind):
==12440== Conditional jump or move depends on uninitialised value(s)
...

And at the end:

this link works if you disable javascript, with OR without adobe flashplugin

enable javascript and have flash plugin installed.  when konqeuror crashes, the following appeared if you do 

tail -f ~/.xession-errors  when you visit web site:

(process:5953): Gtk-CRITICAL **: gtk_clipboard_get_for_display: assertion `display != NULL' failed
Adobe FlashPlayer: gtk_clipboard_get(GDK_SELECTION_PRIMARY); failed. Trying to call gtk_init(0,0);

I don't have flash.

Wolfgang Walter: I lie. There is no flash. :)
Can you tell me what the following commands give you on your system? (This is what I get.)

$ dpkg -L libpcre3
/usr/lib/libpcre.so.3.12.1
etc

$ aptitude show libpcre3
Version: 7.6-2
Depends: libc6 (>= 2.7-1)
Conflicts: libpcre3-dev (<= 4.3-3)

$ ldd `which konqueror` |grep pcr
        libpcre.so.3 => /usr/lib/libpcre.so.3 (0xb632a000)

For me the page works in both 3.5.9 (debian sid) and trunk r804042. Doesn't matter if js is on or off.

Konqueror 3.5.9 doesn't link against pcre for me, but libkjs in 3.5.9 links against libpcre.so.3 (7.6-2). Konqueror in trunk directly links against libpcre (as does libkjs).

BTW: the flash is just one of those ads in top you might hit randomly

dpkg -L libpcre3:

=========================

ldd /usr/bin/konqueror|grep pcr

gives nothing

==========================

ldd /usr/lib/libkjs.so.1.2.0:

        libpcreposix.so.3 => /usr/lib/libpcreposix.so.3 (0xb7e8c000)

        /lib/ld-linux.so.2 (0x80000000)

That's amazing. It might actually be the same package version I have. Could you please check?

My version of konqueror, libkonq4 and kdelibs4c2a is:
4:3.5.9.dfsg.1-2
.. as returned by dpkg -l

These are the version of konqueror, libkonq4, kdelibs4c2a:

konqueror                     4:3.5.9.dfsg.1-2+b1
libkonq4                      4:3.5.9.dfsg.1-2+b1
kdelibs4c2a                   4:3.5.9.dfsg.1-4

I just upgraded my packages to the exact same version you are using and I still can't reproduce the bug. Do you happen to have gdb installed to produce a bugtrace? If so, please do:

$ gdb /usr/bin/konqueror
(...)
(gdb) run

then enter the above site that crashes. upon crash recheck the konsole running gdb and do a

(gdb) bt

Hope that will shed light onto that bug.
