[Digikam-users] Hang while saving or updating JPEG on the network

[Jeff Robinson]

Hi folks,

I'm trying to diagnose a problem I'm seeing with Digikam that has shown
up in the last month or two.  I don't exactly recall when the problem
first turned up, but it's seriously started to cramp my work-flow!

My current set-up is a desktop machine which contains my portfolio drive
and a laptop where I do a lot of my editing.

I primarily use the laptop to edit my photos, with the album directory
shared via a SMB connection (via smb4k).  I've used this set-up for
years, but the problems seem to have only started occurring recently,
and I'm trying to figure out where in my set-up the issue is occurring.

I use the sidecar files for both my RAW photos and JPEGs, in addition to
having the data written to the JPEGs as well.  In what seems like a
random event, I'll update the metadata on a JPEG and Digikam will stop
writing the information to a file, say at 80%.  If I click on the
thumbnail of the JPEG then the metadata commit will complete, but
otherwise Digikam will not seem to finish the write.

If I edit a RAW file in Digikam's Image Editor the editor will now
almost always hang while saving out the JPEG, where previously it worked
like a champ.

I enabled kdebugdialog and get the following output when I save the new
JPEG:

Once I receive the last message about triggering a rescan Image Editor
is stuck at 89%.  If I try to cancel the save Image Editor does not
respond.  If I close Image Editor I receive a dialogue that asks to
"please wait for the image to be saved", but it never progresses.

I can cancel out of the dialogue and have three options: Save Changes,
Save Changes as a New Verion, and Discard Changes.

The only option that works is "Discard Changes".  This seems to close
Image Editor.  If I then close Digikam I receive the same "Please
wait..." dialogue.  If I hit "cancel" then Digikam disappears but a
second "Please wait..." dialogue appears.  Cancelling out of this one as
well makes the dialogue disappear, but Digikam is still running in the
background and I have to manually kill the process.

Any thoughts folks might have on troubleshooting my problem would be
greatly appreciated!
