[KPhotoAlbum] EXIF search now working; "Recreate EXIF Search database" seems to be broken, was: New shapshot

[Jesper K. Pedersen]

Please try and apply the attached patch, and watch stdout for a message, when 
running the recreate db command.

If that doesn't reveal anything, then please send me the strace in a private 
letter.

Cheers
Jesper.

| Hello,
|
| I just tried "Maintenance/Recreate EXIF Search database" another time.
| This time *no* camera is found in the DB afterwards - worse than last time.
|
| What I have seen, is that the progress bar only gets up to 11 %, then
| the dialog silently disappears.
| (Tried this several times) I even tried German and English locale - same
| effect.
| (I have a strace of this; but even gzip compressed it is 424K. Let me
| know if I should post it to the list or send to you by private EMail)
|
| BUT: "Maintenance/Read EXIF info from files" goes to 99 % (And probably
| disappears when reaching 100 %). So there *must be* a difference between
| the two. (Just guessing: Some sort of registered error handler ?)
|
| In the course of that, I also discovered, that KPA doesn't seem to
| detect if two instances are running. Because from my understanding
| SQLite isn't multiuser and the XML file surely isn't, this seem to be a
| really bad idea.
| (This happened on my very first tries for this mail. All observations
| here are without this "user incompatibility" (checked using "ps -ef  |
| grep kphoto"))
|
| Regards
|
| Martin
