Comment 1 Daniel Dedeu 2009-05-14 19:11:28 UTC

Thank you for understanding.

Comment 2 Dario Andres 2009-05-15 00:48:08 UTC

What were you doing when the application crashed?
This looks like bug 190089 / bug 185468 (which are bugs on the Qt library)

@Google translation:
O que você estava fazendo quando o aplicativo travou?
Parece bug 190089 / 185468 bug (que são bugs na biblioteca Qt)

Comment 3 Dario Andres 2009-05-15 15:04:08 UTC

The reporter sent me an email:
----------

I was doing some testing the configuration on the desktop, select to
display the icons on the desktop become the icons of normal plasma and
the normal desktop and then reversed. When the plasma reverses closed
and reopened with these error messages that copied and sent.

---

@Daniel: what is the output if you write "dolphin --version" on Konsole ? You should get your Qt4 version.
Thanks
