Application: dolphin (4.12.3)
KDE Platform Version: 4.12.3
Qt Version: 4.8.6
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Linux Mint 16 Petra

-- Information about the crash:
- What I was doing when the application crashed:

I was was typing an email (using Chrome browser) and wanted to attach 2 files.
From Dolphin I clicked on the 1st file and dragged it into the compose mail dialog. It was ok and it uploaded the file.
When I did the exact same thing to the 2nd file, Dolphin crashed. It didn't even start to uploaded it. Dolphin crashed as soon as I droped the file.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
