Sentry Crash Report:

Description Ansa 2014-04-04 14:16:45 UTC 
This is a new version of bug https://bugs.kde.org/show_bug.cgi?id=332269 which has been marked as resolved before I managed to add relevant information (my fault, I was too busy). I hope it is thus correct to file a new bug on the same topic (I do not have priviledges to reopen the old bug.)

I drag images from Dolphin to the Image toolbar in Parley. Every now and then, this leads to Parley and Dolphin crashing simultaneously. I do not know if this is a parley bug or a dolphin bug, but I suspect parley (dragging images from firefox to dolphin does not cause crashes).

I have mentioned elsewhere that I use stylesheets. This is not related to stylesheets (i.e., the backtrace below was obtained when I was running Parley without stylesheets.) I do not know if this is related to a particular image format - I use mostly jpg/jpeg and png.



Reproducible: Sometimes

Steps to Reproduce:
1. Open dolphin in a folder with some images. I have the dolphin window in the "keep above others" mode.
2. Open parley and make the image toolbar visible. Select some line as if you were going to edit it.
3. Drag an image from dolphin to the parley image toolbar. The image is added to the selected line.
4. Repeat the process until both parley and dolphin crash simultaneously.
Actual Results:

Hi Ansa,

It's definitely appropriate to open a new bug if the issue remains.  Actually you could have told me and I would have reopened it for you but I thought you could do it too.  Sorry.
Comment 2 Andreas 2014-07-05 10:04:10 UTC 
Hello Ansa,
Thanks again for the clear bug report.

I have proposed a patch in:

Comment 3 Andreas 2014-07-06 17:14:36 UTC 
Git commit 5d85ee98a93da6e352532a9a37beb0c6b30dbebd by Andreas Xavier.
Committed on 06/07/2014 at 17:13.
Pushed by axavier into branch 'master'.

Fixes bug 333076 parley and dolphin crash simultaneously when images
 are dragged from dolphin to parley

Problem: Some dragdrop events don't contain any urls. The previous code assumed that all events contain at least one url and would crash when it accessed the non-existent QList[0] item.

Patch: Checks that there is at least 1 url before using the first url.

Note: I was unable to crash dolphin, but I think this is the same bug because the crash occurs on the exact same line as in Ansa's backtrace
