Created attachment 88655 [details] crashreport Crashed right after pressing import button. Import window did not even show up.
Looking at the backtrace, there are two threads that mention ICCPreviewWidget. Are UI classes used in multiple threads? Maybe because of external libraries needing nested event loops?
yes, digiKam use multithreading everywhere. When i said everywhere, digiKam cannot be started when relevant shared lib for multithreading are not installed (typically QThread) So, it's not a threads problem. Sound like an unsupported icc profile embeded in image, which cannot be managed by lcms shared lib. Gilles Caulier
http://qt-project.org/doc/qt-4.8/thread-basics.html states: "As mentioned, each program has one thread when it is started. This thread is called the "main thread" (also known as the "GUI thread" in Qt applications). The Qt GUI must run in this thread. All widgets and several related classes, for example QPixmap, don't work in secondary threads." So while it is nice that digiKam uses multiple threads, it cannot use ICCPreviewWidget outside of the main UI thread.
I know all of this (:=))) But i'm sure that iccpreview widget is not used outside main thread. Note : About QPixmap, it's only true under X11 based env, because X11 is not re-entrant... Gilles
digiKam 4.5.0 have been released. Crash still reproducible with this release ? Gilles Caulier
With 4.5.0, you can still - Start Digikam - Import -> Add images... - Select folder - ... See The KDE crash handler I attached the latest Crash log
Created attachment 89914 [details] Crash log Crash log created by the KDE crash handler, when Digikam crashes while it should import images.
Problem still reproducible with last stable digiKam 4.8.0 ? Gilles Caulier
Can't check: The most recent Digikam-Installer package on http://download.kde.org/stable/digikam/ is 4.5.0 Maybe, you can forward a request to the one who generates the windows installer to be so kind to let it run? (If it'd be that easy...)
Peter, digiKam 4.7.0 for Windows is available : http://download.kde.org/stable/digikam/digiKam-installer-4.7.0-1-win32.exe.mirrorlist Please test and report. Thanks in advance Gilles Caulier
Hi Gilles, thank you for providing the installer! I'll try it this evening and report the results. Peter
Hi Gilles, on my Win8.1-System, the Digikam 4.7.0 you provided is still crashing on import. I was able to do the following: Import-> Add images -> [walk to import folder]-> select folder -> crash I attached the crash log. cu Peter

Not sure if helpful to say "me too", but this has been a bug in the last few 4.x versions for me as well on Windows 8.1. It is still happening in 4.9.0. I'll try attach a backtrace to this ticket.

When the Import window open there was always this message in the console: digikam(9655)/digikam (core) Digikam::ImportStackedView::syncSelection: one or both of the models are null?! from: Digikam::ImportIconView(0x6a6d420) to: Digikam::ImportThumbnailBar(0x6c0c340) I fixed this issue, the crash under Windows it will probably not fix. Maik
This error ("Import-> Add images -> [walk to import folder]-> select folder -> crash") consistently occurs for me using digikam 4.9.0 on OSX 10.10.3, with MacPorts 2.3.3.

meanwhile, 4.10.0 is available. I installed it and the error (chrash while rebuilding fingerprints) is still there. Thanx for the current windows versions.
