Arnd, What do you think about ? Gilles I can't confirm this... light table works just fine here (I'm also using beta5). Thanks Andy. Same for me. i cannot reproduce the crash here... Gilles I can't reproduce that problem either,
and the above backtrace does not really help, right?
Mark, you wrote:

I don't see any open crash reports for the light-table, did I miss one?
(It might be that a couple of crash reports had to be closed, because
those crashes were not reproducible and no back-trace with further information
was available).
Of course it might very well be possible that in certain
situtations one can trigger a crash, so a full back trace
in such a case would be very helpful!
Best, Arnd

Sorry, yes I was referring to those that were closed without a back-trace.
I'll try and generate the backtrack from -beta5 to be of more use.

back trace from light table crash.
Mark, ==> #5 0x0fd4633c in Digikam::ThumbBarItem::next (this=0x0) "This" is null. this is why LT crash. Can you give us exactly all steps done on gui to reproduce it ?

Gilles, I can reproduce using the following steps. 1. Load three images onto the light table 2. Drag the right hand image onto the left and right panes (or Ctrl+L, Ctrl+R) 3. Right click the right hand image and select "Remove Item" (or Ctrl+K) 4. Digikam crash (this=0x0) Attached screen shot just prior to crash. Mark Created an attachment (id=25005) lighttable-crash.png Mark, Arnd, Andy, Yes, now i can reproduce the crash... Who want to check source code (:=))) ? Gilles Ok, now I can confirm it, too. Maybe I'll take a look at the code later on, right now I'm too busy. It seems to crash only if the last image is displayed in the left and right window, otherwise the image will be just removed from the list as expected. Created attachment 25010 [details]

new patch
I think it is more logical to display the last image in the thumbar than the
first one

third patch
When just two images were in the thumbbar and the last one was removed, no
image was displayed in the panel. Now the only remaining image is displayed in
the left panel.
