Comment 1 Marcus Meissner 2011-05-08 16:25:06 UTC

it works for me (as usual) in KDE 4.5.x

can you run:

valgrind kcmshell4 kamera

to see if there is anything special happening?

Comment 2 Rob V 2011-05-08 17:43:43 UTC

It also does it without the camera plugged in (an obvious thing I forgot to
check). Output from valgrind:

[Comment from a bug report cleaner]
The backtrace looks related to the one in bug 236844. Regards

Comment 4 Christoph Feck 2011-05-11 22:13:02 UTC

Marcus, I have another explanation, different from that in bug 236844 comment #7. It could actually be a duplicate of bug 247830.

Rob, is there a difference if you double click on the Kamera icon in System Settings or single click?

Comment 5 Rob V 2011-05-12 09:28:29 UTC

Single click works, double click crashes. I guess this can be closed now -
it's my own fault for forgetting to switch double-clicking on in mouse
settings I guess!

Comment 6 Christoph Feck 2011-05-12 12:38:35 UTC

Rob, it's not your fault, it is a bug in the module authorization handling. Modules can be loaded twice because of the local event loop that KAuth runs. There is a workaround in 4.7, it probably should be backported.
