Description Josef 2012-03-01 21:24:22 UTC

Version:           4.1.1 (using KDE 4.7.4) 
OS:                Linux

My index.xml file got corrupted (perhaps when kphotoalbum closed due to power failure, but not sure). When I tried to start KPhotoAlbum with the corrupt file I get an error message saying 

Error on line 1 column 1 in file /home/josef/Pictures/index.xml: error occurred while parsing element

The only choice of action is the "OK" button. I had to manually find the hidden backup file ".#index.xml" and rename it. 

What I expected was that KPhotoAlbum would handle the situation by offering me an option to use the backup file. 

Reproducible: Always

Steps to Reproduce:
Start KPhotoAlbum with the corrupt XML file

Actual Results:  
KPhotoAlbum throws out an error message and quits.

Expected Results:  
KPhotoAlbum shows an error message and offers to restore the database from a backup.

The corrupt file was too large to upload, so here is a link (~10 MB): http://josf.se/kphotoalbum-corrupt-file/index.xml

Offering to recover from backup if index corrupted

If index.xml is corrupted we check if a backup exists. Then we ask the
user if he would like to use the backup.
