Dr.Konqi crashed after I pressed "Reload" to reload the generated backtrace for the crashed plasmashell. Then another dr. konqi appeard with less buttons and functions as normally saying:

"""
We are sorry, drkonqi closed unexpectedly.
We cannot report this error, because drkonqi does not provide a bug reporting address.
"""
// Can you please provide a bug reporting address for drkonqi?

"""
Details:
Executeable: drkonqi <pid...> Signal: Segmentation fault (11) <time>
"""

And in the tab "Developer information" there is this backtrace:

"""
Application: drkonqi (drkonqi), signal: Segmentation fault

If you can't find a bug here, you can close this. I think, I can't give more information... (I even don't know the version of drkonqi...)
