Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.00 "release 558"
Qt Version: 4.8.2
Operating System: Linux 3.1.10-1.16-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
What is expected to happen: 

-To have a working widget. 

What happens instead: 

- Plasma desktop crashes. 


I use KDE 4.9.0 and Qt 4.8.2 from openSuSE packages (K49R Repository). 

I had KDE 4.7.4 from OpenSuse packages and this widget was working flawless, but now after I made the upgrade, suprise! plasma desktop crashes when I try to add this widget to the desktop. ALWAYS. 

Backtrace incomplete or invalid? I don't know and I don't care, If you, or whoever the hell do so, don't provide debug packages for kdeinit4 and the microblog widget, that's not my fault.  It is neither my fault if you have conflicts with the person who develop this widget, or whatever is behind this packaging hole. So if you want to tell how to get that packages or make a useful backtrace for this widget, I will listen...If you don't, simple, I don't care. 

It is not a bug, just a configuration file issue? Well, why the hell plasma desktop have to crash either? As I had these problem too, but at startup, I just erased the config files that belongs to plasma desktop and I had it working again... Why plasma desktop have to crash when it does not like a configuration file?

Definitively this is not a user-oriented desktop (just a kid's game). An average joe user will install windows after the first crash of plasma-desktop and won't install KDE for windows. 

Good Luck!.

The crash can be reproduced every time.
