Bug 124316

Version:            (using KDE KDE 3.5.1)
Installed from:    Debian stable Packages

Konqueror seems to have a problem disconnecting the kpart within Kaffeine or Kmplayer using Kubuntu (and fedora, Mandriva) packages.  I go to any webpage that plays a video, of any kind, and Kaffeine plays the video fine.  Upon leaving the page, or just closing Konqueror, a crash occurs.  The backtrace of interest is as follows:

To me, it looks as though the qt_cleanup () function is not allowing a clean disconnect.  I'm not sure if there is a bug report for this specifically, but for me, this bug has occurred with fedora core 4 rpms, Mandriva 2006 rpms and now Kubuntu dapper flight 4-5 debs.  Versions of Kaffeine have been 7.0, 7.1, and now 8.0.  The last 6 months of kmplayer releases have given me the same crash.  I see there are some bugs listed as resolved for similar crashes, but I've been experiencing this still.  Thanks again to all who responded to other bugs I've reported on, and thanks to those who look into this and all the bugs that are showing up.
