I see I made a mistake on this:  I had just deleted "all images NOT on disk" -- I mistakenly said "all images on disk"

*** Bug 259401 has been marked as a duplicate of this bug. ***

*** Bug 262426 has been marked as a duplicate of this bug. ***

Please be sure to upgrade all of your Qt, KDE and KPhotoAlbum packages. What source did you use to get them? The error you are seeing suggests that your Qt is broken.

It could help to run the application under valgrind (as in `valgrind kphotoalbum 2 > kpa-valgrind`), work as you normally work and when it finally crashes, attach the "kpa-valgrind" file here.

I installed valgrind and ran:
valgrind kphotoalbum 2 > kpa-valgrind

It did not like the "2", so I then ran:
valgrind kphotoalbum  > kpa-valgrind

after it (or valgrind) crashed, kpa-valgrind was created, but it is empty (size 0 bytes). I tried to attach it anyway, but got an error message from Yahoo! saying that I cannot attach a file larger than 25MB. 
Below is the output that appeared on my terminal. Does this give any idea of what is going on? I have no idea how to interpret this, nor if it is a bug in valgrind itself how to report that. The conditions under which it quit were the same as when KPA runs by itself, so I assume that it crashed, which caused valgrind to quit.

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what OS and version you are using.  Thanks.

Please be sure to upgrade all of your Qt, KDE and KPhotoAlbum packages. What
source did you use to get them? The error you are seeing suggests that your Qt
is broken.

It could help to run the application under valgrind (as in `valgrind
kphotoalbum 2 > kpa-valgrind`), work as you normally work and when it finally
crashes, attach the "kpa-valgrind" file here.

(In reply to comment #5)

There's an extra space in there, it should read "2>".

Please make sure that you either install a corresponding debug or debuginfo for KPhotoAlbum, or build in debug mode. Also make sure you do *not* overclock your computer and run a memtest (like http://www.memtest.org/).

As I said, upgrade Qt to the last version your distribution ships, and in addition to that, upgrade libtiff, too. You also did not mention where your Qt and KPA comes from.

Thank you for your comments.  I ran:
 valgrind kphotoalbum 2> kpa-valgrind
without the space after the "2". KPA ran a lot slower, but at least when it crashed, I got something in the  kpa-valgrind file this time and have attached it. It took a long time to crash. I was viewing the thumbnails, then went away for a couple of hours and when I came back, it had crashed.

KPA, Qt, and libtiff are all the latest versions in the Ubuntu/Debian repositories for my Kubuntu 10.04 (lucid).  I tried to add debugging tools in the "report" window, but it said that there were none available. Perhaps I am looking in the wrong place. I am not very experienced at "building" packages, so I would probably need some clear directions on how to do that if it should become necessary.

I ran Memtest 86+ and no errors were found. I do not overclock my computer.

Does this give you any hints?

As I said, upgrade Qt to the last version your distribution ships, and in
addition to that, upgrade libtiff, too. You also did not mention where your Qt
and KPA comes from.

This looks like a problem with Qt handling tiff files.
If those are not too large it would be great if you could upload them.
