Then just paste in where ever you want the components information as a copy/paste.

There is exactly the same backtrace in #271047

It sound like a crash in Qt4 from my new interface to cache thumbnails for camera interface.

In #271047, it appear when a MP3 file hosted in device is thumnailized by KDELibs.

I cannot reproduce the crash here.

Gilles Caulier

The problem must be related to video files: I had some .MOV files created by a FUJI HS20 in the imported directory; when I removed them the import did not crash any more

yes. Non image file can be the problem. KDE thumb loader is called here.

Can you run digiKam through GDB to have a better backtrace ?

Gilles Caulier

The crash happens in QString, so probably the relevant QString is invalid.
Tracing back, the place where a pointer is turned to a reference is in
CameraThumbsCtrl::procressKDEPreview:

    const CachedItem* cit = retrieveItemFromCache(item.url());
    putItemToCache(item.url(), cit->first, thumb);
    d->pendingItems.removeAll(item.url());
    emit signalThumbInfoReady(cit->first);

Gilles: Can we be sure that cit and cit->first are valid?

Fixed by Andi, i think, with this commit :

this bug isn't fixed at all for me. 
I pulled everything from git to have le latest code and compiled digikam.

But, if i try to scroll down, in the middle of scrooling it will crash with this backtrace:

Veaceslav,

This is a non sence. look like the code is really where crash appear :

CameraIconItem* CameraIconView::findItem(const QString& folder, const QString& filename) const
{
    QString sep;
    if (!folder.endsWith('/'))             // <=== CRASH HERE !!!
    {
        sep = '/';
    }

    return d->itemDict.value(folder+sep+filename);
}

... why ?

Can you place a debug statement to see contents of "folder" and "filename", just before the test ?

Gilles Caulier

http://pastebin.com/bFBP79kr

as you can see, i've got a huge output and only few lines from my kDebug lines...

They are marked as "Content of the filename is" and "Content of the folder is"

Suggested patch

I'm still not convinced about the code mentioned in #7. An entry can be cleared from the cache and the return value must be checked.

Veaceslav: Can you try the attached patch?

Marcel, you were right. It no longer crash on my computer.

Patch works for me.

But, the question is:

why i see all content from my external HDD?
I mean that i can see the content of all folders together and there are mixed everything including mp3, videos and lots of stuff that aren't related to digikam.
 Pressing Download will import lots of things at aren't related to digikam.

also i can barely scroll on that dialog even if i have a top core i5 processor.

Shouldn't i have a option to see directory tree and to select the folder that contains photos that i want to import? Or i'm doing something wrong?

Git commit 2b0b91fa17b05cf367070ce8f4127193d190505d by Marcel Wiesweg.
Committed on 29/10/2011 at 14:37.
Pushed by mwiesweg into branch 'master'.

Port code for KDE thumbnails loading from ThumbnailLoadTask to camera controller,
replacing the existing implementation.

Now, a careful extra hash is kept to map a preview job's result to the underlying
Camera item info. Relying on the QCache does not work because it's a cache, which
means entries may get removed anytime.
Apparently fixes the crash.
