apport kde crashes in QWidgetPrivate::deleteTLSysExt

[Simon Andric]

hello

i filed this under bugs.kde.org already..i hope here is the right place to report this bug...

the thing is like this: a program crashes (typically vlc or firefox-trunk) and then the blue icon apeears in my kubuntu which says a program recently crashed on your system - i click on the icon - a small wndow appears which ask me to either "show details" or "restart program" or "send without restarting" - when i click on EITHER choice - apport craashes and dr. konqi appears with the bug report that apport crashed - since dr konqi works with bugs.kde.org it does not direct me to the right place to file this bug report - since this project is in launchpad.

Hence im reporting it here i hope it helps :)

please if i reported it (again) in the wrong thread, can you heklp me to move it under the right project/package that is crashing...

thank you

nice say

Simon :)
