(*** This bug was imported into bugs.kde.org ***)

Package:           konqueror
Version:           KDE 3.0.1 
Severity:          crash
Installed from:    SuSE RPMs
Compiler:          gcc 2.95.3
OS:                Linux
OS/Compiler notes: Installation: SuSE 8.0 + KDE 3.0.1 Online Update

(N.B.: although there are lots of plugin-related bug reports I didn't find an
identical one. Take my apologies if I missed a duplicate.)

On trying to load
http://www.advancedchessleon.com/princ.htm
I get several message boxes titled "Missing plugin - Konqueror" which ask:
'No plugin found for "".
Do you want to download one from www.macromedia.com?'

After clicking "No" each time (without checking "Do not ask again") I konqueror
caugt a SIGSEGV four out of five times.

Below is the backtrace which was identical in all cases where I checked.

Comment 9 Jakub Suder 2004-02-24 00:16:25 UTC

I'm getting this error in KDE 3.2 from Mandrake 10.0 RC1, on site www.gildia.pl (I'm not sure about other sites, didn't test it much...). A dialog appears asking if I want to download the plugin, and if I click no - konqueror crashes badly (not always, but most of the times).
