            Bug ID: 302095
          Severity: crash
           Version: 4.8
          Priority: NOR
                CC: vkrause at kde.org
          Assignee: kdepim-bugs at kde.org
           Summary: Regular knetattach, nepomuk feeder, dolphin crashes
    Classification: Unclassified
                OS: Linux
          Reporter: phalkon316 at hotmail.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: Nepomuk Feeder Agents
           Product: Akonadi

Application: akonadi_nepomuk_feeder (4.8)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Normal use, 1 chromium window and 1 term window open, surfing web
- Unusual behavior I noticed:
Dolphin takes 10+ mins to open.  First get the icon in task manager saying " -
Dolphin" but no icon, and bouncing Dolphin icon next to cursor for 30 seconds,
then both disappear.  I continue about my business surfing the web, then
10-20mins later, a Dolphin window will open up.  If i click Dolphin more than
once (try to open it say N times), I'll eventually (at least 10 mins later) get
N Dolphin windows that open 1 at a time, even though I haven't tried to open
Dolphin again since the Nth try, many minutes ago.  Once Dolphin is open, I
operates quickly and properly as expected.  I do have 7 SFTP stored folders on
the side bar (below home, network, root, trash, xxGB hard drive) which have
been there for month or so since I installed KUbuntu 12.04, and never had a
problem then.  This has been happening for almost a week now.

Also, knetattach failed to start error upon every login to KUbuntu 12.04. 
Regular "nepomuk feeder" errors/crashes pop up during a session of using the
computer also.  Can't find any error logs with any of those words in them
(using grep).

Every "sudo apt-get upgrade" now ends with:
ldconfig deferred processing now taking place
/sbin/ldconfig.real: /usr/lib/libbrcolm2.so.1 is not a symbolic link

/sbin/ldconfig.real: /usr/lib/libbrscandec2.so.1 is not a symbolic link
although I'm not sure how long that's been happening (at least a week) and if
it overlapped when things worked fine.

The crash can be reproduced some of the time.
