Application: kcminit_startup ()
KDE Platform Version: 4.4.2 (KDE 4.4.2)

-- Information about the crash:
I created four logical partitions when I installed Kubuntu 10.04 as a dual boot
with WinXP.

fstab - 
# <file system> <mount point>   <type>  <options>       <dump>  <pass>

I have been trying to manually mount the "/usr/local" partition without much
success. I created a folder in the /dev/disk folder named "Linux" to match the
"/usr/local" partition's volumn label and then manually mounted the partition
from the terminal, however once I logged out and then logged back in not only
was the partition not mounted the "Linux" folder that I had created for the
mount point was no longer in the /dev/disk folder.

I stumbled upon the System Settings/Advanced/Removable Devices page. I had not
previously looked in this settings page because  the "/usr/local" partition is
not a removable device but a partition on the local HDD in my laptop. I was
surprised to see the "/usr/local" partition listed under its volumn label
"Linux" in the list along with all the other partitions on the fixed HDD. I
checked the box to "Automount on Login".

I then logged out and back in to see if the partition would be automounted. It
was NOT automounted but that's when I began to get the "KCMInit (kdeinit4),
signal: Segmentation fault" crash popup. I then when back and also checked the
"Automount on Attach" check box for the "/usr/local" partition and then
repeated the log out/log in - again no automount and again the same crash
error.

I have now unchecked both boxes of the "/usr/local" partition and again logged
out/logged in with the same resulting error msg. I have never had this error
msg before the above change to the automount settings and have still not
managed to resolve the automount of the partition.

Please let me know if there is additional information you require.

Thank you for your time and assistance,


The crash can be reproduced every time.
