Digikam does not start on Lion

[uenz@…]

digikam compiles on Lion, but does not run: here the result of open digikam.app

digikam(10268)/KSharedDataCache ensureFileAllocated: This system misses support for posix_fallocate() -- ensure this partition has room for at least 10547296 bytes. 
digikam(10268)/KSharedDataCache: Unable to find an appropriate lock to guard the shared cache.  This *should* be essentially impossible. :( 
digikam(10268)/KSharedDataCache: Unable to perform initial setup, this system probably does not really support process-shared pthreads or semaphores, even though it claims otherwise. 
digikam(10268)/KSharedDataCache: Unable to unmap shared memory segment 0x1117aa000 
Dynamic session lookup supported but failed: launchd did not provide a socket path, verify that org.freedesktop.dbus-session.plist is loaded!
digikam(10268)/kdeui (kdelibs): Session bus not found 
To circumvent this problem try the following command (with Linux and bash) 
export $(dbus-launch)

Replying to uenz@…:

Dynamic session lookup supported but failed: launchd did not provide a socket path, verify that org.freedesktop.dbus-session.plist is loaded!

And is dbus-session actually loaded? Please read the output of the command "port notes dbus".

Thats it! I did not now that it is necessary to start dbus manually and unfortunately the error message does not suggest it. Thank you very much for help. Please close this false bug report.

Hello, I have the simillar problem and read those output, but unfortunately I have all of the dbuses running and digikam still doesn't even start. I use Macports 2.0.3, Digikam 2.5, OS X 10.7.3. Don't you have any suggestions please? :)

[ryandesign@…]

Is this still a problem with 2.7.0?

[uenz@…]

In my installation 2.7.0 works with the installed dbus without any issues.
