Description Francesco Cosoleto 2011-12-17 15:09:33 UTC

Application: dolphin (1.7)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1.2-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
1. Doplhin: select a file to drag
2. Alt+Tab to select LibreOffice's Spreedsheet program window
3. Press Escape to close the file requester I forgot open
4. Release left mouse button
5 Crash

Sorry if this is a duplicated issue. No time today to check very well and there are a lot of similar bug reports.

The crash can be reproduced every time.

dolphin (2.0) on KDE Platform 4.8.3 (4.8.3) using Qt 4.8.1

- What I was doing when the application crashed:

try to drag a file from one dolphin window to another.
pretty sure I used alt-tab to switch

I have desktop effects enable with openGL on a nvidia card, if that has any matter.

the backtrace look really similar, although the line number has changed a little bit, I can still follow

thus, it ain't fixed.

as of 4.8.3 (dolphin 2.0)
