Description Wolfgang Bauer 2016-09-23 16:18:24 UTC 
Application: plasmashell (5.7.5)

Qt Version: 5.7.0
Frameworks Version: 5.26.0
Operating System: Linux 3.16.7-42-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Right-click on a file in the folderview applet, choose "Move to" or "Copy to", and select the very same folder where the file is located ($HOME/Desktop on my case).
When the "Overwrite/Rename/Cancel" dialog should be displayed, plasmashell crashed instead.

- This is reproducible with Plasma 5.7.5 and 5.8 beta (otherwise I am using KDE Frameworks 5.26.0 and Qt 5.7.0).

- The crash is in KIO obviously, but I cannot reproduce it with dolphin.

- It doesn't always happen (sometimes the dialog shows up as it should), but most of the time.
Seems to be more reliably reproducible by choosing the destination from the context menu instead of choosing "Browse...", but it also happened with the latter at least once.

- Also reported in openSUSE:
http://bugzilla.opensuse.org/show_bug.cgi?id=1000546

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
