I have a strange effect here, where konqueror is started multiple times.
It is no problem to start it from the K-Menu. But konqueror seems to be associated with different actions in applications, e.g. many "help" entries; among others e.g. Inkscape: "Hilfe/Inkscape Handbuch" (~ Help/Inkscape handbook")
If I'm unfortunate enough to hit such an item, the konqueror items start flooding my task bar, while the mouse cursor - changed to the konqueror icon - is flickering like wild, while konqueror is starting again and again.
None of the windows really open and all icons disappear after some time. (due to some resource overflow, but unfortunately I can't find the relevant log entry this time)

How can I prevent this ? (Or debug this, if the cause is unclear)
