Thank you for taking the time to report this bug and helping to make Ubuntu better. You've already filed this as bug 236989, so I am marking this as duplicate. Please follow the instructions there, which I will repeat and add to here to file a new more useful report:

Edit the file /etc/default/apport and change the line enabled=0 to enabled=1
Next time this crash happens, you should get a .crash file in /var/crash/
You can then file the crash using
/usr/share/apport/apport-qt --crash-file=/var/crash/_my_crash_report.crash
in a terminal - where _my_crash_report.crash is the crash you would like to report.

The process outlined above will automatically open a new bug report which can then dealt with more efficiently. If you do not get a .crash file after enabling apport, please tell us here. In that case, please install these packages:
kdebase-dbg
kdebase-dbg-kde4
libxine1-dbg
and post a new backtrace here, as an attachment. In the future please use attachments instead of pasting backtraces into the description or comment.

Actually, if you get the crash dialog, you won't get a .crash file. Sorry about the confusion.

Please install the debug packages:
kdebase-dbg
kdebase-dbg-kde4
libxine1-dbg
and attach a new backtrace here when the crash happens again.
