Comment 1 Dario Andres 2009-10-21 15:06:28 UTC 
The backtrace is a bit generic (not really useful). If you could reproduce the crash at will a full backtrace (and an explanation) would be very useful.

Comment 2 Christian 2009-10-21 23:07:58 UTC 
Reproducable, i and another guy from a irc-channel can get it to segfault by switching fast through pictures with shift+mousewheel.

Comment 3 Dario Andres 2009-10-21 23:18:14 UTC 
Mh, the backtrace seems to be a bit different...
Thanks. Reopening
Comment 4 caulier.gilles 2009-10-21 23:22:13 UTC

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?
Comment 8 Bartek Pietrasiak 2010-01-04 23:36:35 UTC 
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.
Comment 9 Bartek Pietrasiak 2010-01-04 23:38:35 UTC 
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...
