After a crash, the crash reporter came up. When trying to get a backtrace, it tells me I need debugging information for the following:

* /usr/bin/kdeinit4
* /lib/libQtDeclarative.so.4
* /lib/libQtCore.so.4

I installed the relevant debuginfo packages and reloaded the backtrace, but it still tells me the debug info is missing. However, under the /usr/lib/debug directory, I see these files:

* usr/bin/kdeinit4.debug
* usr/lib/libQtDeclarative.so.debug
* usr/lib/libQtCore.so.4.debug

Is there something else I have to do? Or is it too late to install the debuginfo packages after the crash has happend?

Can you please post the raw backtrace, if the KDE Crash Assistant will show it to you?
It is possible that the stack is being corrupted here, preventing a backtrace from being resolved.

Sorry, I had to reboot since then, so I don't have the reporter up anymore. But if the same crash happens again, I'll provide that info.
