Description Pavel Zheltobryukhov 2009-05-19 22:05:26 UTC 
Version:            (using KDE 4.2.3)
OS:                Linux
Installed from:    SuSE RPMs

Konqueror crashed occasionally (not every time) when videostream opened from http://www.corbina.tv/transmission/ (Moscow Internet-TV Online, Russia)

Step to reproduce 

1. Open http://www.corbina.tv/transmission/
2. Click link to any channel
3. A Netscape plugin popup window appeared
4. Click on MS Windows Media icon and open stream with your favorite player (Mplayer, VLC, etc)
5. Get a crash (or get an error, or get a videotranslation :)

Comment 7 Dawit Alemayehu 2012-01-27 23:15:08 UTC 
A poster child crash for why nested event loops are evil:

#7  0x00d23313 in KParts::BrowserOpenOrSaveQuestion::askOpenOrSave (this=0x0)
at ../../kparts/browseropenorsavequestion.cpp:229

The KParts::BrowserOpenOrSaveQuestion is deleted while inside of one of its functions. Note entirely sure what the reasoning was to create the dialog as the d-pointer object.
Comment 8 Dawit Alemayehu 2013-05-11 16:28:34 UTC 
Can any of you still reproduce this crash? If so, can someone please post a more up to date backtrace (crash log) as well as the browser engine used ?
