Bug 148946

Version:           0.9.1 (using KDE KDE 3.5.6)
Installed from:    Ubuntu Packages
OS:                Linux

My application data is located on a partition which is mounted rw during boot as ~/files. My photos are located in ~/files/photos. This has worked until very recently.

When I try to download photos from my camera to ~/files/photos/<albumname>, the camera window shows the first image downloaded properly (green checkmark above image thumbnail), but the second and all subsequent images pop up the message "Failed to download file "IMG_1239.JPG". Do you want to continue?", and show a red X above the image thumbnail.

Examining the album window, even the image that appeared to download properly isn't there.

In a terminal window, "touch ~/files/test" returns the message, "touch: cannot touch `test': Read-only file system". Mount shows ~/files is mounted rw.

ps -ax shows the following open processes:

After exiting digikam I did the following:

1. Killed one of the digikam*.slave-socket processes that remained open.
2. umount-ed ~/files
3. mount-ed ~/files
4. touch-ed ~/files/test

It appears that once digikam is started I am unable to write not only to ~/files/photos, but anywhere else in ~/files. Killing all digikam processes and remounting ~/files restores write access to my data directory.

I have reproduced this behavior several times.

I believe this is related to the "Failed to convert db to new db format" bug, because I got that message several times (but not of course as I tried to reproduce this bug). I am not using NFS or any other network file access method.
