Mh, the backtrace seems to be a bit different...
Thanks. Reopening

dshareddata trace have been already seen in this room. Fixed by marcel wirh 1.0.0. Please test with beta5 or current code from svn.

Gilles Caulier

digiKam 1.0.0 is out since few days...

http://www.digikam.org/drupal/node/491

Please try with this version coming with more than 400 bug-fixes.

Thanks in advance

This bug may be a duplicate of or related to bug 211238

Report to https://bugs.kde.org

First I can not reproduce this crash, but in imagewindow.cpp line 651: If current index is 0, we are doing --index and then check if index is not size()? Index will be -1 in this case and we will crash. So we have to check for not below 0, right?

The picture which is currently edited must be the first picture on the thumbbar list and I have to go up to get this crash. Until I reach the up border everything is ok.

if you think that some dependencies of digikam are to blame, I can upgrade to try. But which? :]

Bartek,

No backtrace is clear. it's in editor.

Jens,

Yes, test is require there...
